Made us miss our connecting flight

Boarding process was disjointed and weird. Understaffed desk at gate and resulting overwhelm precluded any boarding announcements! Flight itself was fine, with good crew and adequate service. On time with no major delays.

Great staff nice planes.

Boarded late and then sat on plane for 45 minutes because of a clerical error...whatever that means. Then only one truck to deice plane, adding more time to our take off.

Pros: "They let me sleep."
Pros: "good job over all"
Pros: "Entertainment on the flight was fantastic."
Cons: "Delta really struggles with trying to get everyone in the plane in an orderly fashion. Window seats must climb over all of the aisle passengers that got on before."
Pros: "Incredible service, great entertainment options, comfy seats"
Pros: "Good flight."
Cons: "Nothing."
Cons: "Delta scheduled us a connection with only 35 min of layover. We had to go from Concourse E to A and the plane was several min late.We barely made it before the gate closed 10 min before pushback."
Pros: "New airplanes.On time schedule .Very professional a"
Cons: "Could not get my boarding pass from Delta for the flight from PHX to LAX. Aeromexico did not confirm that leg of the trip, so I lost all day and had to buy another ticket for tomorrow. Still, Aeromexico has not solved anything"
Cons: "Full flight and tiny seats surrounded by 2 300lb guys and they wouldn't let me switch my seat."
Pros: "I am on stand by after 24 hours. Because delta airlines was late.im stuck in LA"
Cons: "It was cold"
Pros: "got to the plane even though the ground crews had a lot of people to get bags checked for even down to 30 min to flight departure but still got their bags onto the plane"
Cons: "massive rips in the bag"
Pros: "Everything except food. I asked them for halal food when I bought tickets. But they didn't serve me halal food. Very very disappointed."

Pros: "Airport was being remodeled so there was a bit of confusion and lack of accommodation but other than that the flight was good"

Pros: "Fast flight"
Cons: "Long wait in hot plane before take off."
Pros: "The Flight crew was great and the pilot got us there with the least amount of delay as possible. Thanks everyone!"
Cons: "The redesign of seats means that very few of Delta's planes can actually accommodate a sherpa-style pet carrier, even though they are an industry standard for in-cabin travel. Further complicating the problem is that the clearance under the seat varies depending where in the cabin you're seated. It's become an extremely stressful proposition for which I have the privilege of paying an extra +$100 each way whilst having to give up one of my carry ons. As far as I can see, the charge is just straight up greed, since no one would be able to use the space beneath the seat in front of me, anyway, and carrying on my cat cause zero extra work for the crew. I'm going to have rethink my loyalty to Delta. At least with Southwest, they'll let me check two bags for no additional cost."
Pros: "Smooth. Fast."
Pros: "very attentive service and remarkably tasty food in first class"
Cons: "seat was tight. not much legroom and very claustrophobic when the person in front of me reclined his seat."

Cons: "norte americano gringo scum from hell usa terrorist pigs"
Pros: "Nice"
Cons: "Check point had only one person working on a holiday weekend made for an extremely long wait"

Pros: "The crew was polite and helpful"
Cons: "The plane was 30 minutes late arriving in MSP"
Pros: "Check in was fast, didnt interact with any staff! It was great."
Pros: "Crew was professional, courteous and kind. No issues on the plane."
Cons: "WiFi did not work for me to watch the on board entertainment, but not a dealbreaker for me."
Pros: "The trip was as to be expected. The low cost was the absolute best thing about this trip. If the cost is going to be that affordable, I will definitely take more trips with sun country and recommend it to my friends and family."
Cons: "The only issue w/the flight was that we sat on the tarmac for about as long as the flight took. There was something going on at the gate we were to arrive at, and that left us on the tarmac for about 45 minutes or so. Then there wasn’t very good air flow. Should’ve had an alternate gate."
Pros: "They didn’t let me on I want a refund this made me miss my birthday party in Chicago thanks for ruining 25"

Pros: "Everything...thanks!"
Pros: "At least there was a USB port to Charge my phone."
Cons: "The flight was three hours late and suncountey lost my luggage. When I looked at my claim ticket it had someone else’s name on it."
Cons: "The wait time at the airport."
Pros: "Everything about the fligh was excellent."
Cons: "The ONLY thing that spoiled it was an unusually long wait for bags once we arrived home. Why you would have 6 flight coming in to the same carousel I will never understand. To wait for more than 45 minutes to see the first bag come down is awful & put a huge damper on an otherwise stellar flight."
Pros: "Nothing special."
Cons: "Both flights were late 15-30 minutes leaving the gates."
Pros: "I was able to get an aisle seat."
Cons: "Turning all the lights on at beginning of descent-I was sleeping. Flight was late because of previous flight coming in to Phoenix."
Cons: "Having to pay for carry-on luggage! I have a CPAP and have to carry it on. NOT cool Sun Country. Your cheap fare just went off the chart."
Pros: "Non stop flights the only plus"
Cons: "Boarding staff was totally rude and unprofessional I will never fly sun county again!"
Cons: "I could not get a boarding pass on either flight, going or returning; the Sun Country website is a disaster. Also not happy about its new baggage policy."
Pros: "Staff"
Cons: "1. No warning about change in carry-on policies. Really crappy. 2. Online check-in- no warning that exit row seat assignment must be checked in in person at counter- added burn- no refund for the upgrade. Really awful. I won't fly Sun Country again."
Cons: "We paid extra for exit row seats they did not recline and seats were SO uncomfortable...not your fault I know just saying airlines in general have gone downhill."
Pros: "Clean plane. Plenty of leg room."
Pros: "Wheelchair assistance"
Pros: "It was nice"
Pros: "Check in wxcellent"
Cons: "Service slow on airline. Only seemed to cater to first class"
Pros: "the crew were good. and they gave us $20 meal vouchers and $200 travel vouchers"
Cons: "the airplane broke in boston and we were stuck there for 7 hours before we could board."
Cons: "My flight time was changed multiple times, the final change was not communicated and myself along with other passengers missed the flight. Employees refused refunds, failed to apologize and/or provide a phone number to reach Sun Country. Did not offer to reschedule or assist in finding another flight. Overall seemed unorganized, unhelpful, and common courtesy for customers was not exhibited. Never flying with Sun Country again,"
Pros: "I loved my flight but there was no snack unless you pay for it"
Pros: "Easy and painless. In fact, while I was getting my bag checked at the gate, the Gate CSR noted that there was an aisle seat available and asked if I wanted to move from a middle seat to the aisle. At 6'3", I was very grateful for the ask."
Pros: "Friendly crew, flight left and departed on time, good value for the money. Terminal 2 at MSP is really convenient. Can't comment on the food, I didn't eat on the flight. I don't need to be entertained. I will definitely fly Sun Country again."
Cons: "Seats are cramped."
Pros: "We were allowed to free check some carryon bags due to full plane."
Cons: "So crowded with the narrow aisles. Attendents constantly bumped aisle passingers with rolling carts. Aisle arm on my seat would not come up despite repeated attempts to push button."
Pros: "Flew down Tuesday and back Wednesday - all flights were on time and everything went smooth."
Cons: "When we got to the counter for our return flight, they told us Olivia's flight was not paid for. I couldn't believe it, as they never said a word on our way to Phx. She had already been assigned a seat along with my other daughter & I. Our 3 tickets were booked at same time and were all charged at once!"
Pros: "Crew were very nice. I'm sure it was the end of a long day for them, so they were probably ready to be done - more interaction between themselves than the customers."
Cons: "Seats not very comfortable. Too bad that comfort has to be given up for profitability..."
Pros: "On time"
Cons: "Although seats were assigned when purchasing the tickets, I wasn't able to print boarding passes that allowed my travel companion and I to sit together"
Pros: "Everything was on time and efficient."
Pros: "We made it home alive, stewards smiled a lot"
Cons: "No one at desk for check in, then when boarding there was a man standing in the aisle that would not allow me to pass, I had an infant in my arms but he refused to move even after multiple requests. I had to squeeze past him. When plane was fully boarded he started to vomit. He vomited multiple times before we started moving. Steward asked him if he was okay to fly and he did not answer, just nodded a bit. He continued to vomit, was unable to use the bag properly, he appeared highly intoxicated. He vomited into the aisle and all over our shoes and pant legs and carry on bags. We told the stewards who went and grabbed a package of paper towels and shoved them at us. They moved the passengers on the other side of him up to the front of the plane but said nothing to us. No one apologized. Twice we were told our baby was the baby of the year but that was the only remark."
Pros: "The crew was pleasant, kind and observant to passengers needs. Plenty of smiling. The beverage selection was truly fantastic. We were informed of any changes and the crew was very accommodating."
Cons: "The window seat that I requested on the way home was just a blank, white wall. I noticed quite a few passengers that waited a bit long for the return of their credit cards because of a slow, faulty or outdated card reader."
Cons: "Being delayed and disorganization around the need to have more people check their bags"
Pros: "Better leg room than some other airlines. Flight was on time. Let us check our bag at the gate = faster boarding.no food"
Cons: "No food or entertainment, should have a 'not applicable ' rating."
Pros: "Seat next to me was empty so I had room to stretch out and relax with armrest up!"
Cons: "We were late boarding in PHX but no explanation was ever given as to why?"
Pros: "Doreen L, our flight attendant was so kind and cheerful to us and everyone she served. She is definitely one of if not the finest flight attendant at Sun Country!"
Pros: "Great service! Comfortable seat. A+."
Pros: "Friendly customer service. Efficient boarding. Liked being able to board early because I did not require overhead bin space."
Cons: "Complimentary pretzels or other light snack would be nice."
Pros: "The crew was friendly and accommodating. I forgot that Sun Country serves cheese burger hamburgers, keep them on the menu."
Cons: "People switching seats prior to take off in the airplane. This needs to be enforced that people need to stay in their assigned seats unless approved by the crew."
Pros: "I got to my desinations on time to and from."
Cons: "The seats were small and uncomfortable. It felt like I was squished into my seat both flights, and that was even being on the aisle. While I don't expect every seat to be made for an obese individual, having enough space in the seats so as not to require scrunching your shoulders every 20 seconds would be appreciated."
Pros: "Smooth process, direct flight."
Cons: "No peanuts or treat of any kind"
Pros: "Excellent service all around -- from baggage check and pre-boarding process to inflight delivery and early arrival. I also loved departing from terminal 2. Great job Sun Country!"

Pros: "Awesome Customer Service"
Cons: "Nothing"
Cons: "Nothing. Awesome Customer Service"
Pros: "The flight was probably one of the worst I've ever taken. The seats and aisles are so narrow. You had to walk side ways to get down the aisles. Very uncomfortable flight. It was so bad I had to upgrade to first class on the return flight because I just couldn't bear it again. I was not happy ."
Pros: "4 flights and all of them in middle uncomfortable seats. I requested aisle seats many times and counter agents were unhelpful and rude."
Cons: "Better seat options and more comfortable seats"
Pros: "Overall a very good flight"
Cons: "Awful, loud credit card sales pitch wine up children and another everyone in cabin for what seemed an eternity. Absolutely disgusting."
Cons: "No advanced seat assignments unless we paid $100 per person?! Recently flew Delta on same equipment (A321). Delta had in-seat entertainment & adjustable head rest"
Pros: "Made it to destination"
Cons: "Gate changed without any notification"
Cons: "As soon as I boarded I noticed a strong urine smell. It didn’t really go away, or I just got used to it."
Pros: "The comfort of the plane and the continued update on my flight delay."
Cons: "The flight was delayed but no fault of American."
Cons: "We boarded a bit late. No big deal. Once on, however, they made us deboard because they forgot to do a security check. Oops. Flight attendants made the experience much better -- funny, enthusiastic, hard-working."
Pros: "The employee who checked me in was very helpful - found my frequent flyer number for another airline and give me a free checked bag."
Pros: "Easy flight"
Cons: "too tight to connection time in DFW"
Pros: "Customer service people were nice."
Cons: "American Airlines broke my carry on luggage handle and was told that I couldn’t claim it even though I was told that I had to check it in. Airplane was cramped, felt really uncomfortable"
Pros: "Always prefer American air over most other airlines do the service of staff. Thanks for the extra effort."
Pros: "blanket made it comfortable"
Cons: "No entertainment options"
Pros: "Staff was awesome!"
Cons: "As was getting in line for security, overheard it was at least a one-half hour wait. The wait was actually pretty close to 1/2 hr."
Pros: "Was able to get my flight transferred!"
Cons: "I liked Everything!"
Pros: "This was the same crew and pilot from the flight I took to LAX. His landing was so smooth, I woke up pleasantly upon landing!"
Pros: "The trip was on time and with no issues flying. I really enjoyed the ability to watch a movie...this was AWESOME!"
Cons: "Wow, the seating was VERY tight and I was happy for the TV screen in front of me to keep me busy. All the inflight interruptions on the movie I was watching."
Pros: "Planes were on time and staff was friendly"
Cons: "Nothing disliked"
Cons: "Flight was changed. Didn't get the seats I had already picked out. Woman on flight was very rude to me when I asked where the restroom was. NOT a good experience over all."
Cons: "Flight delayed going to and from my destination with no compensation. My bag I had to wait for it to come on the next flight and had to wait 2 hours for it."
Pros: "Standard flight , however I can't believe what most passengers bring on as cabin baggage !!"
Cons: "Evening meal of a turkey sandwich on dry bread was forgettable and considering that they co-share with Qantas , American could learn about providing a decent meal on a long expensive flight"
Pros: "Checkin was fast. Crew is always pleasant."
Cons: "Seats are uncomfortable. I chose to upgrade my seat and was charged but i couldnt see any difference between my seat and anyone elses. I dont understand how it works. Then I was refunded the upgrade amount..."
Pros: "After missing my flight and zero empathy from AA employee who reassigned a new ticket - I was given 3 new times and an explanation that no pilots were there yet. Flight was short and painless -- but the scheduling was totally frustrating."
Pros: "I love the cookies"
Cons: "I wish my seat would recline more"
Cons: "The flight attendants were not very pleasant; almost pretentious. One had a passive aggressive attitude towards an older couple next to me with questions regarding the exit seats. The flight attendant was short and quick to snap. This was the couples first trip to hawaii and the attendant gave them a sour impression leaving the plane. I was disappointed."
Pros: "Everything was nice and comfy"
Cons: "Nothing everything is perfect"
Pros: "Bathroom!!"
Cons: "There were no screens by each place!!"
Pros: "The lay over wasn't bad at all had enough time to make it to my gate and get something to eat"
Cons: "Was scheduled to leave at 3:15pm didn't leave until 4:17pm"
Cons: "Our flight was delayed due to weather, which I was fine with as I wanted to fly home in the safest conditions, and I do trust the captains decision. However, upon arrival, we were stuck on the runway for 3 hours!!!! Our flight landed at 1, we did not exit plane until 3:40. They were not curtious enough to give us accurate time frames on when we would be allowed off. They told us 40 minutes initially, obviously was a lie. We did not receive updates whatsoever. We had to stay seated the entire time with seat belts even though we were not moving!! I got up to use the restroom and was instructed to sit back down even though attendants were aware that we were not moving and were not getting off any time soon. A 2 hour flight turned into 5 hours on the plane instead so of course many passengers needed to use the restroom. Flight attendants offered no avail with extra attention, drinks, snacks or even by allowing fussy babies to be strolled down the aisle as the aircraft was completely still until the last 3-5 minutes when we FINALLY pulled to a terminal. We had to have a terminal when southwest would have gladly brought stairs to our flight so we could at least wait inside a less compact space, such as the airport, for luggage. I know of many people on our flight who missed connecting flights, which I'm sure AA did nothing to accommodate. By the end of it all, my family member who originally was going to pick us up from airport went home as he waited over 3 hours for me to get off the plane. I had to pay a taxi cab to bring me home and did not make it home until 6am when it was all said and done. To add insult to injury, the flight attendants did not even thank us for our patience or have the decency to address said issue. Never flying AA again."
Cons: "Terrible side to side of aeroport to get conetion fly with out time"
Pros: "The crew was wonderful. Our flight was delayed 3 hours and they did their best to keep all the passengers comfortable and happy."
Cons: "There was no food or entertainment to rate"
Pros: "I was in group 2"
Cons: "Nothing"
Pros: "Crew was friendly. Seats comfortable for economy. Routine pretzel/cookie/peanuts and beverage. The crew picks up the garbage almost immediately after giving it me...huh? Then I'm left holding it the remainder of the flight when the come back through again. Now for the kicker....I had two flights the same day so I opted to buy the All Day Pass for $25.95!!! What? It was a 2 hour flight each way... Can't they prorate for flight duration or something??!! I ended up watching 1 movie "Superman vs Batman" that was 1 of 4 options of movies that come with the $25.95 package. Other movies available are an additional $5.99 to "rent". Wow...ruined."
Cons: "See the pro section it won't let me copy and paste into the con section."
Pros: "See above."
Cons: "See above."
Pros: "This is what every flight should be like."
Cons: "Pretzels was only free snack."
Pros: "Window seat"
Cons: "Unorganized boarding. Not a smooth flight. Landing was questionable."

More leg room

The check-in process couldn't have been worse. Besides they have no customer service to speak of, I wasn't able to purchase a 2nd checked bag prior to the trip, the app just wouldn't let me no matter what. I spent over an hour on hold waiting for a rep who wasn't able to help me. At the airport we politely asked the rep to help since we were unable. She flatly refused to do anything. When we asked to speak to a supervisor she said she was one of the most senior people there and if "We're still not happy she can give me a number to call where I can wait on hold for over 2 hours to be told the same thing I'm telling you now." Absolutely atrocious. First and definitely LAST time flying Allegiant.

Pros: "Flight was great overall."
Cons: "Timelines was very poor. 2 hour delay because we don’t have a crew is terrible!"
Pros: "direct flight"
Cons: "airport hassles"
Pros: "the non-stop flight works very well. lay overs are never welcomed, but tolerated because they need to be"
Cons: "hard to think of anything"
Cons: "The boarding process. And how the flight attendants speak to the customers; I found a bit abrasive and insensitive for no real reason."
Pros: "This crew was amazing"
Cons: "The seats are very hard."
Pros: "Flight speed"
Cons: "The crew needs to remember that we are all watching and listening to them hoot and holler with themselves. During the flight the head attendant was watching a movie on her personal device. At this point anybody could do her job"
Cons: "Pathetic rationale for delay"
Pros: "I like I can pick seats."
Cons: "Ppl putting their carry on in overhead bins nor in their row so when zone 6 (at the front of the plane) gets on, there’s no room in your overhead bin space. Crew should say to passengers to put their luggage in their area, not front of the plane."
Pros: "Cheap and direct no frills"
Pros: "Flight attendants were very kind, attentive and caring. There was a special needs girl in the same row as me that was by herself and they were always making sure she was okay and comfortable as well as the rest of the plane."
Pros: "Crew was friendly, boarding process was easy, spacious aisles"
Cons: "The seats do not recline and are not very comfortable. Drinks and snacks are not complimentary"
Pros: "The plane was clean and crew was very friendly."
Cons: "Delayed departure with no explanation. Other passengers clogged up the overhead bins with small bags, purses and containers of to-go food. Causing me to place my carry on in an overhead bin multiple aisles behind my seat which made for a cluster trying to board and de board."
Pros: "Price of ticket. Crew was efficient."
Cons: "Baggage limitations are not clear: especially when the ticket says no carryon luggage. What they mean is anything that fits under your seat and is under 20 lbs is OK. Seat did not recline. Leg room was poor."
Pros: "Very efficient. Arrived early."
Cons: "Seating very tight."
Pros: "I finally got home"
Cons: "We took off 3 hours late. No transparency about what the delay was or how long, they just kept stringing us along 30 minutes to an hour at a time."
Cons: "it was very hard to hear the stewardess"
Pros: "Efficient, direct flight, outstanding price, quick boarding, left late but arrived on time"
Cons: "Nothing. I did not try food or entertainment on this flight."
Cons: "Long delays"
Cons: "I bought a flight that I had to end up cancelling - when I called to cancel - within the 24 hour period, they would not let me cancel despite text on my confirmation saying that there would be a free cancellation within the 24 hours. Extremely annoyed that there was a blatant miscommunication. I did not end up going on the flight but was unable to get a refund which seems ridiculous given that there was text on the website explicitly saying this was their policy."
Pros: "On time"
Cons: "initially assigned to center seat."
Cons: "Bags charge for 105$"

She showed up, then they made a announcement that the Oakland flight will be delayed till 8:10 takeoff. I was able to get on a flight to Stockton Airport without problem. They wouldnt tell me what was wrong, and i didnt want to chance that it was the last dlight to Oakland and went with Stockton. The flight was good, you have to pay for your water."

Cons: "Very small and uncomfortable seating will probably fly Delta for the same price"
Pros: "It was cheap and was no different than other flights I have taken."
Cons: "Their station at the airport didn't open until about an hour before my flight."
Cons: "Plane was clean. Leg room was adequate for a 6 footer. Wafer cookie was good. Crew was nice."
Pros: "The crew was friendly but because of 5 flight delays we missed our connections in Amsterdam and got stuck in Houston for the night."
Cons: "The crew was friendly but because of 5 flight delays we missed our connection to Amsterdam and got stuck in Houston for the night. Because of this we were forced to pay for a hotel in Houston. I believe that we should have received some type of voucher for the huge inconvenience and waste of money"
Pros: "Easy check in and boarding, friendly crew, comfortable seating."
Cons: "No suggestions."
Cons: "Crew was really inattentive and service was poor to say the least. Very disappointing business class experience."
Pros: "Seats were very comfortable in first class. Very happy with that experience for short haul flight. Enjoyed the service. Flight attendant checked on me multiple times and offered beverages."
Cons: "Snack/food choices."
Cons: "We got delayed due to maintenance, captain tells us to get off flight, then retracts, then tells us it will b longer than expected, so majority of people get off and he then comes to gate to tell us to get back on plane, majority of passengers had connections! I waited 2.5 hours to Rebook next day!"
Cons: "after boarding, we sat on at the gate for nearly 30 minutes without any explanation given. When announcements were made the person's language skills were greatly lacking - we could not understand anything that was said. there is no food, drink, or entertainment... unless you consider the man behind me playing with is cat .... and yes I'm very allergic :( landing crew didn't know where our luggage was to be returned (bottom of the gate or top of the gate). After a considerable time, we were told all luggage was delivered to the baggage concourse."
Cons: "United has a 2 hour delay for mechanical issue. We almost missed our connection to Zurich. Our bags did not make it and we are still waiting for our luggage"
Pros: "Nothing"
Cons: "The flight was delayed."
Pros: "Timely departure"
Cons: "Annoying screaming 4 year old with his mom’s inability to control him. They sat in front of us. From Houston to Baton Rouge - attendant was too slow. Couldn’t get a cup of water to anyone except I am assume first class passengers. No notice. No apology. Disappointing!"
Pros: "The flight attendant refilled my ginger ale without me needing to ask. Smooth flight until we approached Denver. Always hit turbulence when landing in Denver."
Pros: "Nothing"
Cons: "Rude employees - never flying with United again."
Cons: "I didn’t not like being delayed an entire day because they had a problem with my wife’s name in the system"
Pros: "In-flight entertainment Good leg space Comfortable seats"
Pros: "The counter clerks in the airport were not friendly. But the inflight attendants and service was great."

Pros: "Good crew!! Entertainment screen not as good as SAS"
Pros: "Smooth flight"
Cons: "Nothing"
Cons: "Horrible customer service"
Pros: "short uneventful flight"
Cons: "no services provided"
Pros: "Seats are not comfortable and it is hard to sleep on this flight"
Cons: "Seats, crew."
Pros: "I booked a basic economy seat & ended up on a small plane, that was fully booked. It had 2 seats on either side of the aisle but it was surprisingly comfortable."
Cons: "The flight was short so thankfully I didn't have to pay for entertainment. It's a loser move to make the customers pay for everything; luggage, food & entertainment on my international flights, I always go for the companies that try to make the passengers comfortable and I'm going to think the same way on my local flights in the future"
Cons: "There was a delay in boarding then another delay in getting off the ground because of stand bys getting on and off. Turbulence was bad and there was no announcement for it. Just a long bad flight! Lots of crying kids and babies!!"
Pros: "They were very helpful, but there was so much turbulence it made me really sick."
Cons: "Boarding"
Pros: "Ease and Comfort. Each terminal in our two-leg journey was modern, immaculate and simple to navigate. The flight and crew were outstanding; attentive and professional. Keep up the good work!"
Cons: "We just couldn't justify paying 16.00 so each of us could watch TV for two hours. We would have appreciated basic TV, in order for us to stay on top of the National/World news. We feel it is part of our best interest, as a country and world, to keep informed. Please allow for at least BBC to be viewed. For Free. Thank You."
Pros: "Crew was mostly friendly"
Cons: "Leg room has vanished"
Pros: "Seats have some good cush to them"
Cons: "I specifically bought carry on luggage that meets the standards so that I would not have to go baggage claim as it would weigh heavily on my schedule. As I stood in line and noticed all of the huge "carry on" bags more than 2 I was astounded when the flight attendant said my carry on would have to be loaded with the other luggage. When I offered my rebuke she scolded me and said the luggage would be there before me....how the hell is that supposed to happen? To make matter worse the flight "attendants" stopped serving half way and when they started again I got trapped by the bathroom and did not get back to my seat in time to enjoy a beverage....not that I was offered one."
Pros: "I'm glad I didn't get kicked off!"
Cons: "I did not like the boarding process and I had a fear of being kicked off."
Pros: "The updates I received on my phone for delays and change of gates was faster than the agents would/could announce."
Cons: "When workers were walking the aisle, it was hard to get their attention."
Pros: "The flight was on time. Boarding on and off was good."
Cons: "The in flight wifi doesnt allow streaming. It was lame and there was no free in flight movies. So other than sleeping or using an app to text there was nothing you could do. In flight wifi isnt worth buying."
Pros: "The flight was average. Nothing stood out bout what I liked."
Cons: "I didn't like that my seat didn't recline. The temperature was very warm. Boarding took an exceptional amount of time and it was chaotic as we all stood in group lines for long periods of time."
Cons: "I decided to take another carrier in the aftermath of United's terrible treatment of paid passengers/customers. United doesn't deserve my business (ever again)."
Cons: "Last row - very large man that should have needed two seats !"
Pros: "Everything"
Cons: "Nothing"
Cons: "Decent"
Pros: "Very quick ride"
Cons: "The seats don't sit back that much but it wasn't bad because of the short flight."
Pros: "Organized boarding"
Cons: "Economy is very cramped"
Pros: "Courtesy and helpful"
Cons: "I don't have any complaints"
Cons: "No entertainment"
Pros: "My morning started by finding out my flight was delayed an hour and I was in an immediate panic that I would not make my connection. An hour turned to 1.5 and I was sure I would miss my best friend's wedding. The flight attendants were put in a horrible position - a flight full of delayed pasangers and they had nothing to do with it. The attendants and pilot were SO accomodating and empathetic and assured me they were in a good position to make up time. Between your staff and the free directTV and the fact that I made my flight with 5 minutes to spare....my trip was saved!"
Cons: "Could have lived without the 1.5 hour delay...but it happens."
Pros: "Efficient crew, friendly service,"
Cons: "Delayed flight both ways. Free program wasn't watchable on my device because I didn't have their app downloaded."
Pros: "Very good service and great pilot"
Pros: "Like other airlines, United is charging more fees for seats to food. And the food they sell is bad. The breakfast was microwaved to horification. Why are airlines permited to give such low levels of service? Why are they allowed to charge extra fees for ordinary seats? And no complimentary entertainment. All that NOTHING" service and for very high fees.I got suckered into paying a lot extra for premium Economy. The Premium was the extra money they stole. The Economy was the new definition of bare bones."
Cons: "There was nothing to like about the flight."
Pros: "Flight times were accurate."
Cons: "As soon as we arrived to the airport, checking in was the biggest hassle. We were harassed by a guy working the ticket counter named Guilermo. He was EXTREMELY rude and continued to harass us and followed us after we checked in and we're already at the security check point. It's $25 to check a bag but if you check 2 bags their website says its $35 for both. We were charged $50 to check two bags. Even after Guilermo told both of us that they wouldn't charge us for the second bag to be checked. The guy that checked our bags was also extremely rude and clearly didn't care. Once we started boarding the flight several passengers had to check their bags at the gate because there "wasn't enough room on the plane". Not really sure how this was fair since we had just paid $50 to check two bags and were lied to about it when several people just checked their bags for free. We chose to fly with United because of the good deals they have on flights but after our experience I would MUCH rather pay more money and have a lot better customer service. We had such a horrible experience it almost ruined our first day of our week long trip. I'm. It really sure if it's obvious to the employees of United but traveling for most people is a very special occasion. This occasion happen to be a very special one to us as it was a family vacation and seeing family we haven't seen in years. The poor attitudes and rude demeanor from the United staff is all we could think about even after we reached our destination."
Pros: "The friendly and comfortable atmosphere!"
Cons: "PHX is a large airport, and my emailed ticket said Brussles Airlines, Terminal 4. First off, Brussles Airlines is not a carrier at PHX, and secondly no one knew that United was their partner. There was no information provided to me to go to United, which was in Terminal 2. After making a phone call to Brussles Airlines, I ended up getting to the check in gate ten minutes after boarding started. It was a lovely rest of the trip after that though! But please include partner information im the email next time!"
Cons: "Super annoying toung boy who kicked my seat and slammed the tray table al ost the entire flight...obviously not United's fault."
Pros: "I got a super cheap fare for this short flight from PHX to LAX. Staff was courteous and the flight went smoothly from start to finish."
Cons: "Was unable to figure out the free entertainment offered. Was a short flight so I didn't really worry about it."
Pros: "The only positive was that the seat next to me was empty so I had a little more room."
Cons: "Flight attendants were unpleasant and plane was very dirty. My seat also felt sticky."
Cons: "Food"
Pros: "The price Phoenix to LA and back for around $77"
Cons: "I got the shitty set by the exit door that didn't recline no big deal on such a short trip"
Pros: "Can't beat the ease of flying especially considering how quick arriving into Los Angeles verses driving"
Cons: "Delays due to presidential speeches"
