Find cheap flights from Trenton to San Francisco

"Frontier seems to be trying to be a good airline. Gate communication and baggage checkin are weak communication points."

"The boarding staff were rude, and the in flight staff consistantly peddled their credit card"

"Changed gates and didn’t make announcement for those already in airport on layover. I missed the flight and have to purchase another flight and stay over in the city missing work"

Pros: "Because I was unwilling to pay for seat selection, I was prepared to be separated from my husband and stuck in a middle seat. To my pleasant surprise, the agents put us in the same row by ourselves."
Cons: "Better directional signage in both the SFO and Las Vegas airports (arrivals). Las Vegas is a huge airport, requiring a tram to get to the passenger pick-up, even with directions it was confusing and not obvious. In SFO, half the plane walked halfway down the concourse in the wrong direction because of lack of signage and it looks like the right way to go. Drop Kiwi as a third-party for domestic flights, their customer service is clueless, handling charges absurd and flight requirements unnecessary."

Cons: "My experience was ver good. I think the Crew for frontier did a great job. There was so Many people checking in. They got everyone Throw check in and to there flights"

Pros: "Affordable pricing, plane itself seemed to be in good condition. All of the crew was pleasant except one employee."
Cons: "I was embarrassed by the crew member as I was finding my seat. She asked if I had relation to the gentleman who I was to be sat next to. Once he and I replied no, they began laughing. I asked what was so funny and another guest said "it's going to be a long flight", to which she replied "Maybe you will, but I won't." She also told me that I couldn't keep my 11 month old child in the carrier but failed to mention she's only not permitted in the carrier during take off and landing. This also made for an uncomfortable ride. Had these things not occurred I would given this flight a much higher rating."

Pros: "Flight wasn’t bad for what I paid for. One MUST definitely do his/her homework before flying to be prepared for all of the extra costs, etc... I was glad I did and was prepared with my own food, neck pillow, etc. I didn’t expect much in terms of creature comforts and therefore wasn’t disappointed. There isn’t much space in the cabin, so I was glad to have my 6-year old in between us 2 adults. Crew was pleasant r and professional. Ticket agent was helpful if a bit “assertive”. I probably won’t try to book them for long flights, but for short flights their fine"
Cons: "The tiny space and small seats!"

Pros: "The stewardess' were professional and friendly"
Cons: "The flight was delayed, the captain stuck in traffic, and they boarded the plane in the Florida heat without having the AC on. A real health hazard! At first they said that it had to be the captain who could turn it on. He wasn't even in the airport yet! It wasn't until I complained about concern for my child's safety that they called for someone to plug it in. The flight price seems like a bargain, but the individual charges for bags and seat assignments feel tricky and in the end doesn't make this a deal. The comfort on the plane is horrible. If I would have known the seats were unpadded, and the tray tables worthless I would never have booked this flight. My husband couldn't work on his computer as the tray table is miniscule. I have never flown this airline and will never again. There were multiple places in our row that had gum stuck on the floor. Gross. Never again Frontier."

Cons: "They didn't know how to handle the unpleasant situation of having delay due to "the plane is having some problems and they will try to fix it asap before departure"."

Pros: "price"
Cons: "Flight delayed 7 hours. Called the airline after receiving a flight delayed text, and before heading to the airport, and was told to get there by 5pm because the flight may leave on time. Departed at 2am on a Sunday night instead of 7pm. Was told 3 different stories for the delay. Departing airport weather, although blue skies and all other planes taking off on time; plane arriving from an airport that had grounded all flights when Frontier was departing to said airport as they reported this story, mechanical failure, etc. Took a picture of the departures board where all other airlines were departing on time to all locations. Asked if food vouchers would be provided and told, "no". Then vouchers were provided 2 MINUTES before all restaurants in the airport closed. The vouchers had a print time of 4 hours earlier. They would not rebook on another airline and would only rebook on Frontier 3 days later. Zero customer service. Employees were rude and complaining that they had to work late while their customers would be arriving home at 5am after booking a flight that would have allowed time to sleep before work. This is on top of no carry-ons, entertainment, or even water on the cramped, packed flight."

Pros: "Ticket prices were initially really low."
Cons: "Everything else about my experience with frontier. They nickle and some you at every corner. When you go to pick a seat that'll cost you $5-$25 per seat. Then you're looking at $35 per checked bag $40 PER CARRYON. The only time I have ever paid for a carryon bag. No complimentary water/beverages/snacks. The seats are hard plastic with very little padding and no reclining. The tray table is smaller than your average tablet. On our departing flight we sat on the tarmac for well over an hour with no explanation. Horrible customer service all around. I will never be flying frontier again."

Cons: "First I bought a ticket from Spirit Airlines SFO to MCO for 309$, then I saw charges from frontier Airline, frontier airlines bought a ticket for me too for 287$, when I was just watching checking the price. Then I compared the tickets, both the time, but from Frontier Airlines was cheaper then I stayed with frontier and cancel the other reservation from Spirit Airlines the next day I see frontier airlines also cancelled that reservation and I had to rebook another ticket for 496$, the price went up, then I had to pay 187$ extra, IT WAS A FRAUD JOB FROM FRONTIER AIRLINES, I can prove everything above with the receipts and the dates on it, the worse experience I had"

Pros: "First off I've never flied on Frontier before. I've heard some pretty negative things about Frontier but booked a flight anyways because 1) it was 1/2 the cost of any other airline for the dates I wanted 2) it was a non stop from SFO to MCO so how bad could it be. It was absolutely horrible and enough to convince me to never book a flight on Frontier again. Here's some things that you should know if you've never flown Frontier before. They charge $25 for carry on bags and $30 for a checked bag as long as you purchase ahead of time. If you show up at the airport and pay there then the cost for a carry on is $50 and a checked bag is $60. You are allowed to bring a personal bag for free as long as it's not bigger than 18x14x8 and that's what I did. You can't choose a seat on Frontier unless you're willing to pay an additional $12-$42 so you essentially get whatever they give you. The plane was an A319 but the most stripped down version that an airline could probably purchase. The seats don't recline and it's basically a plastic seat lined with fabric. Extremely uncomfortable to say the least. The employees for Frontier across the board are very unprofessional and rude, at first I just thought it was an isolated incident but the more contact and interaction I had with Frontier's employees the quicker I realized that it's company wide the level of unprofessionalism exhibited. If you want a snack or anything to drink including water you better be ready to pay a premium, so it was a rough 5 hour flight. On the way out of SFO my plane was delayed over 3 hours. When I asked about the delay they said it was weather. The funny part was that only Frontier flights were delayed. Flying back my plane was supposed to depart at 6:55pm but we actually didn't depart until 11:15pm. Lesson learned and I know that for me I'll pay the extra money to fly with a carrier that I have experience with that better caters to my traveling needs."

Pros: "None"
Cons: "The flight was delayed 5 hours, and we were offered a $100 voucher that would be emailed to us immediately after the flight takes off. I approached the desk to verify with an employee pre-boarding to ensure I will receive this voucher. She was annoyed with me from the start repeatedly saying it will be emailed after takeoff, which was NOT my question. My question was to verify that the email on file was correct. She had a very hard time getting this to her head. However, it has been over a week and I have yet to receive this voucher. Unless, I receive this voucher I will never recommend this airline."

Pros: "Crew was pleasant"
Cons: "They charge for: a checked bag, a CARRY-ON bag, and your seat choice. There is no on-flight entertainment. The seats don't recline. The check-in counter has massive lines of people and is clearly understaffed. The gate is frequently empty and abandoned with zero people to answer your questions. Flights are late without good reason. Gate agents are understaffed, uninformed, and frazzled. Gate changes were poorly communicated and disorganized. Frontier management and leadership: you should be embarrassed."

Pros: "The crew."
Cons: "My first flight was canceled without notice, it was a 1:30AM flight. Had to sleep in the check in area of the airport until we could get our next overpriced tickets that will not be taken care of by their 3 options they give you. This shouldn't have been placed as the cheapest tickets available with out big red warnings that it is only cheap if you have no bags. $40 more would have given me free check in bags and a far better in flight experience on another airline. Spread the word to never fly Frontier."

Pros: "What did I like? A safe and smooth flight from San Fran to Chicago and back."
Cons: "The seats are cramped and don't recline. I'm an average weight and height and normally don't have such a hard time resting despite long flights, but both flights were uncomfortable. In addition, the flight from Chicago to San Francisco was HOT and no drinks are offered without payment - everything on Frontier is extra $$$ - a bit of a turn off. I'm an avid Southwest customer and I think I will be going back to them even if the flight 'seems' cheaper when searching Kayak. I appeciate you asking about my experience. I love Kayak, but won't be flying Frontier again. I'd rather spend up to $200 more for Southwest to get: comfy seats, free bags, cabin temperature comfort, on time flights, drinks and snacks. It's worth it."

Cons: "They charge for everything, even carry-on! If you don't tell them you have a carry-on, they will charge an additional 20$ on top of the $40 for the regular charge. They charged me even to make a check-in online and assign a seat. Only water is served in the plane and if you want soda you gotta pay for it. Ridiculous! The counter crew are rude and seemed overworked. The airplane seats DO NOT lean back and they have no foam, only a hard piece of leather covering the metal seats. They put their price very low on the travel websites and get you that way. Later on the fine prints (which no one ever reads, btw), they state that there are extra charges for everything else. I am surprised that they didn't charge me to breath inside the plane! Im Chocked!"

Cons: "The price was good, before you realized the price was a lie and they scam you by charging $45 to carry on or $40 to check a bag! That meant the overhead space was unused and they were just charging more just to be inconvenient. The plane was stripped barebones. The crew were rude, did not smile, and gave me attitude for hitting my elbow with the drink cart. They charge for even getting a soft drink. Nothing about the experience said "we're serving you." It's worse flying a more expensive airline because the rediculous bag fees make it just as expensive and even things that should be free like pleasant staff were lacking."

Pros: "nothing! the flight attendants were nice!"
Cons: "only three rows of seats recline! the most uncomfortable flight ever! I thought (ALL) airlines would have all their seats except exit row seats recline? especially on a cross country flight! my girlfriend said she never had to pay for a soda on an aircraft! I have no problem paying for checked bags, but for a carry-on, I have never heard of that until I flew Frontier this weekend. JUST NOT HAPPY AT ALL WITH FRONTIER AIRLINES! my girlfriend will be filling out either this survey or your facebook page? we thought we were the only folks complaining, but felt a little better when people seated around us had the same complaints! I have never complained about an airline before this."

Pros: "I liked that the plane flew safely."
Cons: "Both my flights were delayed which caused a lot of inconvenience given that this was a short trip and time was of the essence. The second time I kindly approached the counter to ask if a drink ticket or free wifi could be extended as a courtesy. The woman at the counter was snarky to me and made under her breath comments as I walked away. I understand now that frontier does not have wifi but she was very rude. I think this was the tipping point for me. I was trying to be ok with the unexpected charge for a carry on. I think letting passengers know in advance would serve in Frontier's best interest since this is an incredibly unusual charge and one I have never heard of from any other airline. The people at the counter who explained this to me as I checked in were also rude and snarky. I felt that Frontier provided absolutely nothing past a the actual flight. The seats dont recline, not even a centimeter, the tray tables are too small to place a drink and a sandwich on it and it seemed every Frontier flight in the airport was delayed. The icing on the cake is how nasty the customer service people were. I've experienced rudeness from other airlines before, but at least we landed on time and I didnt suffer back pain for 2 days afterwards from the incredibly cheap lawn chair style seats. Please improve your service. I know your whole bit is you wont provide any amenities so you can pass down the savings to the customer but it's not really a cheaper flight if when you get there you have to pay an extra $60-80 for a carry on?! Grow your company, provide outstanding service and pay your employees enough that they dont behave like they're at a dive bar. On the upside I do believe the pilot was sober."

Pros: "Nothing"
Cons: "I didnt like the fact that I couldn't talk to someone here in the United states for frontier. I didn't like that when I called customer service I was instructed to do the wrong thing and fill out the wrong form. And most of all I really hated that my flight was cancelled and my money put into a "shell credit" and when I went to re book the fight it cost 3 times the amount than I originally paid. Overall this has been a horrible experience and I will be tell everyone I know and even people I don't know via Facebook, Twitter, Instagram and snap chat about my experience . Overall I feel your service and your service provider failed miserably."

Pros: "Price"
Cons: "You risk losing the flight unless you pay additional fees to select a seat in advance. If you do risk getting your seat assigned at the gate (no fee), you MUST be first to the gate to get your seat assignment because they far oversell the flight. Interestingly, they seem to intentionally punish people who avoid the seat assignment fees in this way. My evidence for this is when my husband and I were first in line at the gate for a seat assignment, the agent said that there were no seats together and gave us seats far apart. However, the girl behind us in line ended up sitting next to me, meaning that the agent purposefully seated my husband and I apart. In addition to all this, you must pay for SODA. And there is no entertainment, as the seats are thin plastic and squished as close together as possible. Consequently, the seats have laughably small tray tables. In summary, I will never fly Frontier again."

Cons: "1. They charge for every little thing. Each checked bag is $25.00 and each carry on is $35.00. They also charge you for a seat. So once you purchase your ticket, you then have to pay an additional fee to seat down. 2. The staff is unprofessional. Not only does everyone look sloppy, but the staff is comprised of individuals that don't care at all about customers and have been poorly trained. The quality is very low. 3. I was hit and then verbally abused by a gentlemen on the plane, they laughed and did nothing!!!!! 4. They only allow 15 bags on their plane! After 15, they will move your bags to a different plane without telling you. What kind of nonsense is that?!"

Pros: "Everything was awful"
Cons: "If I could give this rating a 0 stars, I would. I never plan on flying with this airline again. The attendant was extremely rude at the beginning when I tried to check in and I almost had to miss my flight because she was trying to charge me for a bag that was a carry on (charge me triple the amount) and that fit perfectly on the overhead, I even took a picture. She was extremely rude and unprofessional and put a hold in my account trying to get me to miss my flight. Luckily, the attendant at the boarding gate was already having a bad day due to the incompetence of his fellow coworkers and just let me go on. It was horrible. 0 stars, worst airline and flight ever"

Cons: "I will never fly this airline again! The tix appear significantly cheaper on kayak, so we drove 2 hours out of our way to ATL in the early morning hours thinking it was saving $$$. Only to find at check in that it cost more to bring a small carry on than to pay for it to be checked! It was a west coast flight and it didn't even include a beverage in flight!!! No snack either. Thumbs down. It was certainly NOT worth the inconvenience of driving out of the way, and we didn't save any $ after all. The staff was not that friendly, at it took 30 mins for the frontier baggage carousel to even start up to get the heck out of there. Never again. If it seems too good a deal, it is!"

Pros: "The flight staff was really nice and provided excellent customer service :-) I felt sorry for them that they had to work for such an incompetent airline and field so many customer complaints."
Cons: "In response to Frontier's survey question, "How could we serve you better?" Be more transparent about your hidden costs, and be sure there is a gate available when you land. There were delays coming and going. In Denver we sat on the runway for at least 20 minutes before we found a gate and could get off the plane. In SF we sat on the runway for over an hour (!) with the engines running. My throat was sore from breathing carbon monoxide fumes. The friend who came to pick me up in SF was kept two hours past her bed time because that was the totally amount of delay. To add insult to injury, you had the nerve to CHARGE for coffee, and worse I paid $160 in baggage fees round trip, making you MORE expensive than competitors, not less like it appears when you buy the ticket. I did try to look up your baggage policies on line and by phone (which referred me to the website and gave no option to speak to a person), and it was not easy. The only information I found before I lost my patience was that we would be charged more if our bags exceeded certain limits. The original charge was cryptic and hard, if not impossible, to find. We were told both coming and going about staffing shortages and employees calling in sick. If you treat your employees like you treat your customers, no wonder they don't want to come to work! Not only will I NOT recommend Frontier to my friends, but I will go out of my way to DISCOURAGE them from flying your airline."

Pros: "I booked Frontier for the low price. But after going to a farther away airport and paying for bags and seats and drinks and sitting in an uncomfortable seat, I am not so sure it was a great deal. I am happy that I did pay less than other airlines even with the cost of checking a bag (less cost than carrying one one) and for the seat. Because it is more costly to carry on a bag, hardly anyone did leaving lots of room in the overhead compartments and speeding up boarding and deplaning considerably. Snacks and drinks were reasonably priced and lower cost than in the airport. Only snacks like chips and beef jerky are available so if you want food, bring your own. Flight attendants were friendly. My bag arrived on the same flight that I did and it was in good condition. We were reasonably close to on time."
Cons: "Seats are short front to back and don't recline. There was barely enough room between seats to force by backpack down to the floor and almost no room on the floor to hold it leaving me with no where to put my feet except on top of it. My legs are long and about 1/2 of my leg was not supported by the seat. This was manageable for a short flight but I would certainly not book a long flight with these seats. We spent considerable time on the tarmac waiting at both ends. I am not clear on the delay at the beginning of each flight. The delay at the end was related to Frontier only having 1 gate at each airport so we had to wait until it was free. Yes, we landed 20 minutes ahead of time, but we got into the gate 20 minutes late - meaning sitting on the tarmac for 40 minutes. Bags were slow to come up. Probably because everyone checked them so there were many."

Cons: "Boarding - people who sit up front go first meaning that those that have seats in the back have to go in past people who are still in the aisles arranging themselves. I could not get a drink of water without paying. Is it really that esxpensive to give a coke and some peanuts??? Paying for seat selection means that some people get in the seats other peoiple want (like window seats) who don't want them. I tryly believe that Frontier is the nickel and diming airline. And I don't believe you had to wait for a gate and 11:30 at night."

Pros: "Easy check-in."
Cons: "Hidden charges for carry-on luggage was an unpleasant last minute surprise and added an unwarranted $55 to the cost of the flight. Had I known the flight really wasn't the advertised price, I would have picked another carrier because their price would have included everything. Frontier seems to charge for every little thing but the air you breathe in the cabin. I suppose that will be next. Frontier used to be really good and now it is aging planes, unhelpful staff, and nickel and diming their passengers to death. Next time we will fly with another carrier."

Pros: "That they got me to my destination safely."
Cons: "This airline is a joke. Shame on me for booking late and choosing the cheapest ticket. BUT knowing what I now know, I would have selected the Delta flight for $80 more. Here's why: No TSA Pre-Check. This aspects alone is a deal breaker. Pay for carry-on bag AND IT COSTS $40. Pay for beverages, snacks. Seats don't recline - "pre-reclined for your maximum comfort." Whatever Tray table is metal and tiny. You couldn't even fit an iPad mini on it, let alone a lap top. So, I put my MacBook on my lap to work, but it's uncomfortable, MacBook slides off. You're hitting the person next to you with your elbows. AND I have to take off my jacket, to protect my MacBook against hitting the metal tray table, so I got cold. No internet. It's 2016. No internet. It's 2016. Never again."

Cons: "Worker at the gate was not friendly at all but crew on board was better. I had my 83 year old mother traveling with me & the cramped seating was a little too aggressive. After everyone boarded, they were still trying to sell some of the empty extra legroom seats and I feel at that point they could have sold them at a bargain. I hated to rate Entertainment a 2 but there wasn't any at all. Ive been flying Frontier for about 6 years and it's a shame they now charge for carryons and have been charging for seating for awhile. I'm sure I will fly frontier again in the near future but I feel that the extra charges took a lot away from the excitement of obtaining a good deal. The pilot seemed very competent and friendly."

Pros: "overall the aircraft and schedule was ok"
Cons: "Our luggage did not arrive at our destination. It was an absolute nightmare to get it back!! I had to call the airline about 50 times, where most of the calls were not answered. I had to keep calling and following up. When the luggage did come they only delivered one of the 2 pieces. The calling marathon had to be resumed most of which went unanswered! We finally had to rely on the delivery company to provide alternate numbers where there was a possibility to get an answer. Absolute nightmare!!! Never never will I travel this airline."

Cons: "I was helping my mother - in - law check in and board - she needed wheel chair assistance. We were in line to drop off a bag that we had checked in online an hour before the flight. There were 5 people in the line with only 2 reps helping. Since I hadn't printed the boarding pass, I tried to print the pass at the self-help kiosks getting the message that I needed to see an agent. The cut-off for checked in baggage is 45 mins before the flight, however the reps were making no effort to expedite the service. In 15 mins they had helped 2 people making us the 3rd in line and the line had grown to an additional 5-6 people behind us. 45 mins before the flight they refused to take in any bags for checking - in. Since I was able to take the checked in bag with me, I asked that the agent print the boarding pass for my mother in law and call for wheel chair assistance. The agent called for wheel chair assistance but refused to print the boarding pass! The one thing that the ticketing / check in agent should be able to do is to print a boarding pass for a reservation that is fully paid. Because of this my mother in law had to miss her flight and we paid an additional $99 to get onto the next flight. I was so taken aback when the agent refused to print the boarding pass, that I did not even know how to convince her to do her job. This is probably the worst experience I have ever had with any airline!"

Pros: "Both flights were on time. There was no difficulty with boarding, everything proceeded in an orderly manner with no untoward delays."
Cons: "Misleading information regarding carry-on baggage. Extra charge if I assigned myself a seat when I printed my boarding pass the night before the flight. Extra charge for every, little, thing. $1.99 for 3-4 ounces of Coke. 3-4 ounces of warm water with no ice. Seats that did not adjust. Minimal service from the flight attendants. On early morning flights (both of mine departed at 6 a.m.), when everyone was snoozing as well as they could, a flight attendant came on the VERY LOUD pa system with a commercial trying to get us to apply for the Frontier credit card. I will AVOID flying on Frontier in the future, and use it only as a last resort when I can't get a flight on ANY other airline (as was the case with this last-minute, necessary flight). It is the first time in over 30 years of flying that I had a BAD experience."

Pros: "Very nice crew. Arrived early. Modern spiffy cabin, seats are molded on backs so a bit more room for passengers. I loved being able to add a tip on food bill, a way of expressing appreciation for the crew has been missing for too long."
Cons: "Seats don't recline! I think my back started to hurt because I couldn't change seat; standing up helped. There's no charge for carrying on personal items but I saw a family with personal size shopping bags that was shocked to learn that a carry on suitcase wasn't a personal item and woul cost $60 (can that be right?). I tried to help them and could see that their English wasn't too strong. They hadn't understood the clear written rules and were severely punished to the point of crying - they won't fly Frontier again."

Pros: "The flight was very smooth and the crew was very courteous."
Cons: "I also don't understand having to pay for your carry-on. At least make the first one free. I understand it's more along the lines of weight for the plane and which would affect the amount of fuel but that should all be calculated when they review the passenger manifest and assume that people have at least one carry-on and then adjust fuel accordingly for people who want to bring more than one carry-on. I gave food and entertainment a one star because my flight was a short flight and we didn't get really either of those except having to buy snacks and some soda"

Pros: "Trenton Mercer airport was small and convenient. The crew were very friendly"
Cons: "I had to pay $45 for a small carryon, which I've never ever paid for a carryon all the times I've flown. I purposely did not pack a luggage to save cost. $45 is more than I would have paid for luggage with American and carryons are free. The seats didn't recline and there was very little leg room. I paid $200 for my ticket not including my carryon fee which was so unexpected, then if i wanted a drink, that was an extra charge. Are you kidding me? This was my first time flying frontier and I was disappointed."

Cons: "Just a super cheapo airline that offered an "inexpensive" ticket that then they charge you for everything else, with no warning about the hidden fees. Like baggage: you can't take on more than one free, tiny check-in without paying at least $35, if not much more. Uncomfortable seats. The flight was 3 hours late when a neighbor flight to the same city (on Southwest) took off on time, and so they gave us this lame $10 voucher to appease us, and yet we couldn't use it anywhere, just pissing you off more. They wouldn't accept it at the airport or on the plane, so, what the heck?"

Pros: "Getting OFF the plane"
Cons: "The new seats are flat out terrible. They're thin, poorly padded, and uncomfortable after only 15 minutes of sitting on them. I'm 6'-4", tall, but not a giant and my knees were against the seat in front of me. Legroom was nonexistent. When the stewardesses came through with food and beverages, it was $2 for a can of soda. So after paying an extra $30 to check one bag, and then paying ridiculous prices for a can of soda, and getting cramps after a 2-hour flight with no legroom, Frontier has moved to the bottom of my list for any future flights."

Pros: "Frontier staff in SFO (San Francisco) friendlier to passengers than ORD (Chicago). Kept luggage at SFO for pickup when I arrived"
Cons: "Missed flight by 10 mins. Was able to check-in 1-hr before a domestic flight and get my boarding pass printed. However, the attendants were not interested in expediting me, and 4 other passengers going on the same flight, through security. Ultimately, 5 passengers with boarding passed missed their flight even though we had arrived to the airport and checked-in at an appropriate time! After the plane left, an attendant assisted a passenger to rebook their flight, but then left to go on break and left 3 of us stranded. Very few Frontier attendants available to help us. Had to pay $225 for another same day flight to SFO using American Airlines. Learning points: - hard deadline, need to be at gate 10 mins before departure time - lofty and esoteric reimbursement process - Frontier does not participate in TSA Pre-Check, so arrive 2 hours ahead of departure time for domestic flights - Frontier does not participate in other airline organizations, so unless you rebook with Frontier you are paying full price for the new ticket"

Pros: "Nothing. Worst airline ever. Rude, incompetent staff."
Cons: "The $60 charge for carry one that I discovered as I was about to board the plane. In 42 years of travel, never been charged for this. My bag ended up being more expensive than my flight! I thought I had found a $49 bargain flight on Kayak, and it ended up being a red herring. I feel completely ripped off. Not to mention, I saw a member of the flight staff treat 2 passengers ahead of me with very little respect. I was not the only passenger fooled by the carry-on scam. This entire experience with Frontier was like a Quentin Tarrantino movie. Never again!!"

Pros: "Our flight didn't get canceled."
Cons: "I did not like that the airline does not mention anything about paying for carry on, paying for all drinks and food or paying to choose a seat, which were extremely uncomfortable by the way. All of these costs combine could have equaled or exceeded other ticket prices. It felt misleading and not worth the effort. I also thought that the sales pitch on the flight was disruptive and annoying. If you are going to represent yourself as a budget airline, stop trying to nickle and dime me everywhere you can."

Pros: "Nothing"
Cons: "Everything. Frontier is awful and I will never fly with them again. They cancelled the flight for "weather" more than 12 hours in advance. By the time the flight was supposed to leave, flights were taking off from O'Hare without any problem. Next, they could not have been less cooperative in helping my find an alternative route to San Fran. After more than 2 hours of arguing with Frontier personnel, they magically found a way for me to get there via Denver. Finally, once I boarded the flight to Denver, the crew could not have been any less competent. I saw at least two instances where they had given away the seat of someone who had checked into the flight, then had to scramble to find them a new seat. Frontier is the worst."

Pros: "The boarding process was easy enough."
Cons: "The crew was absolutely clueless. Half way through the flight no less than 6 sleeping passengers were woken and shuffled about because they discovered two other passengers had seated themselves in the priority area. I understand the desire to ensure passengers are seated properly. However, it was ludicrous to wake 6 people who were not at fault for this error on their part. They should have been more vigilant at the start, or left the rest of us alone after the fact. Terrible understanding of customer service. Also, our flight arrived early, however, they didn't have the appropriate gate available. Poor planning as we knew we'd be early about half way through the flight. Would not fly again, not because of the disorganized gate business, however, there's a real lack of customer focus on this airline."

Cons: "Frontier has trained their staff and written their website to "threaten" passengers into buying extra's like bags, assigned seats ."if your bag doesn't fit we will charge you 120 at the gate", I cant' guarantee a refund" "you may not get a seat if you don't buy one online (they warn you three times on the website before you can complete online check in...we were "randomly assigned" 6 seats together for free by skipping the buy seats step and completing online check in). On frontier you can only take one personal item for free. carry on is $70 (35 one way) and checked bags are $60 (30 one way)...MORE at the airport. I also fault Kayak here, they don't compare apples to apples - united carry on bags are free.. I bought 5 checked bags (6 people flying), but we decided to just do a personal item in the end. Turns out you can only get bag refunds at the airport ticket office ..not online or by phone. The ticket agent said there was no guarantee we would get a refund, but she would put a note in our record. Hmmm....prepaid $300 for a service we didn't use and may not get refunded. Online check in tries to bully you into buying seats...you have to say no 3 times before they let you complete check in. That would have been another $120 for the 6 of us. The best for last. On the return flight home, we went to ticketing agent to get refund for return bags ( the outbound ticket agent would only put a note in our record for the outbound flight, so we had to stand in line again for the return flight). She told us there was a gate change and sent us to the international terminal (a different terminal than the rest of Frontier flights). She marked the new terminal on our tickets. We were at the gate for 45 minutes and realized there were only about 10 other passengers for our flight there. I tried to call frontier on the white airport phone. They just had a recording and told me to dial an 800 number. I was on hold for 20 minutes before i got a person who said he couldn't get me any information. The flight wasn't listed on the departures board in the international terminal we had been sent to, so finally we decided we'd better go to the original gate. We had to go to another termanial, go through security again, and found our flight boarding at the original gate. The woman who sent us to the wrong terminal was at original gate loading passengers, so she knew there had been a mistake. She said they had made two announcements. The trouble is, the announcements were not audible in the international terminal. I told her there were several other passengers at the wrong gate, one of whom was elderly and would need help making the flight, No apology, and when we continued to try to get help for the other passengers, they, told us to move away from the podium or they would call security!!! ARGH!"

Cons: "They offered cheap tickets to lure my friend in (she paid for my flight to her wedding as I just moved to another state and was strapped for cash) and only when I arrived at the ticket counter, did I find out that I had to shell out an additional 45 dollars FOR A CARRY-ON!! So, I had to pay 90 dollars, which I didn't have, AND pay for snacks and a beverage, because nothing was open at airport at the time of my flight. The flight crew was mediocre at best, as the flight attendants didn't bother to greet anyone except for the only man in a business suit. If you're going to nickel and dime people, I think it better to charge a little more for everyone's ticket, instead of slamming them with hidden costs. Overall, this experience left a bad taste in my mouth that even the 2 bucks a piece in-flight sodas couldn't wash away."

Cons: "I did not like the fact that I had to pay for placing a carry on in the overhead compartment, when most airlines do not charge for that. Also, the price for a carry-on was more expensive than a check-in bag. Then our flight was delayed for 3 hours and the board at the airline still showed "On-Time". After we landed in San Francisco from Las Vegas, we were stuck on the tarmac for 45 min. and could not leave the plane. While waiting on the plane I was how your baggage handlers were literally throwing the passengers luggage because they failed to drive the cart closer to the conveyor belt (now I know why luggage looks discombobulated). When we were able to leave the plane(we were off loaded at the international airport), the flight attendant failed to announce that our luggage was moved to the domestic terminal. She only announced that our luggage was going to be at carousel #12. Both the international and domestic terminals have a carousel #12. All the passengers waited at carousel #12 in the international terminal for at least 15 mins. Then when we found out it was at the domestic terminal, we all had to walk about 1 mile. My overall first time experience with Frontier was absolutely horrible. The staff was very unhelpful and did not inform the passengers properly which cause the passengers more time at the airport and less time at their final destination. Terrible, terrible airline. I would never recommend this airline to anyone at all."

Cons: "$45 for a carry on! The announcements on the flight were entirely about what you could not do, should do. It was like we were in the military. No friendliness other then when we landed thanking us for flying Frontier. Gate Agents said in response to me running to the gate 30 mins prior to the original scheduled departure (because the monitors were saying final boarding) when the flight was delayed an hour...."well at least this way everyone will be here for when we do leave/ Really? That makes it a good idea to have passengers running to the a gate just to wait another hour. I was in row 4...seats in front of me reclined and our row did not...fortunately I was not affected by the person beside me in the middle seat was...poor design to have people in row 4 have already tight space reduced significantly due to person in front reclining the seat."
