Pros: Cheap and easy flight

Cons: Maybe complementary beverages and snack

Pros: The lady crew members were well dressed, helpful and very nice.

Pros: Cost was reasonable

Cons: Room on flight

Pros: I had to change my flight and you charged me close to 500.00 from Denver to Fort Lauderdale! Rip off!!!!!

Cons: I had to change my flight and you charged me close to 500.00 from Denver to Fort Lauderdale! Rip off!!!!!

Cons: If the flight had not been cancelled!

Pros: It was a modern plane

Cons: Very cramped. No snacks. Food cost money. Tv cost most. I'm a skinny person and I had very little room to be comfortable. I enjoying flying but this flight was very uncomfortable

Cons: Delays

Pros: We landed safe

Cons: I Paid for preferred seats. When we got to the airport our seat assignment changed. We were not in the seats I paid extrs for. No money offered or returned.

Cons: I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER.

Pros: On time flight, bag made it, great price, can’t complain.

Cons: Seat pretty tight for an average size adult man. No inflight phone charger.

Pros: The staff was friendly and helpful

Cons: Outlets to charge my electronic devices for the long flight

Pros: The flight timings and the arrival time

Cons: I was told I MUST pay for my carry on and the woman at the gate told me it was unnecessary, after forking over $45. Also, water cost money on the flight. I felt mislead.

Pros: Flight was also Over one hour late. Bags took over 30 mins to arrive

Pros: Staff was friendly and flight was quiet.

Cons: I once loved Frontier and used them exclusively. Now, however, their new seats destroy my spine before taxiing from the gate. It is the most uncomfortable airline I have had to use... ever! I feel like their planes are so overpacked that, were there ever an accident, just getting out of my seat would pose a challenge. I willl avoid them at all cost in the future. It is no fun fkying in those seats for 3hrs then trying to enjoy your destination. Never again!!!!!

Cons: The flight was delayed three hours

Cons: Support for all Android platforms needs to be updated.

Cons: The crew missed 6 rows in their beverage service and when someone in those rows asked to be served they acted like the rows were lying, my row was one of the ones skipped and when they begrudgingly came back to serve us they ignored the Chinese man sitting next to me and didn't bring him anything to drink they also refused to serve a snack when someone wanted to buy one. If I can ever fly other airlines than United I do and this experience confirms why.

Cons: The fact that United forces basic economy customers to check carry-on luggage is nothing but a cash grab. Some of the overhead compartments were completely empty yet they force you to pay ?30/ bag. They also gouge you an extra $25 per bag if you bring your carry on to the gate.

Pros: Flight was on time and very smooth. People were very nice and friendly.

Pros: Delta in flight entertainment is great.

Cons: Always delayed.

Cons: The flight was delayed three hours

Pros: Good fare nice crew

Pros: Nothing

Cons: Out of the four frontier flights I’ve taken in the past six months each one has been delayed for some reason. First one was over an hour late and caused a majority to miss connecting flights. Today’s experience was not a whole lot different. First leg of the trip was behind schedule, second was delayed at the terminal for the “cleaning” of the aircraft. I will walk to my destination before ever flying with frontier again

Pros: Crew was friendly, take off and landing were good!

Cons: Just a general observation I notice the more I travel...I really wish they would stop making the aisles of planes so small!

Pros: We left early and arrived early.

Cons: Vents were weak. Way too warm.

Pros: The flight attendants were awesome! Very helpful and attentive.`

Cons: I was told that I would have internet onboard the flight. I was very much looking forward to that. When time came to connect, all I got was inflight onboard local network. No texting, no watching of football games. I would not complain had I been told up front there was no internet access.

Pros: The staff were so great and friendly - From the airlines counter to all the crew members. We're very helpful and kind while checking my dog below. Super pet friendly

Cons: Both flights were delayed

Pros: The crew was really friendly and the seats were comfortable with more legroom in coach than most other airlines. I did not partake of food or entertainment, so gave one star because there was no box for "n/a"

Cons: Arriving 20 minutes late to Seattle, which was the fault of the airport, not Alaska Airlines, but it still affects my rating of the trip

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

Cons: Left very late with very poor communications that kept changing as well as the gate info!

Pros: Equipment was adequate. I liked the on board emergency instructions!

Cons: Boarding was chaotic—no lines, just a mass of people all trying to get to the same place.The crew did their job but weren’t particularly friendly.

Pros: Crew was very nice

Cons: No drunk option other than orange juice or water, and orange juice gives me heartburn so more options necessary

Cons: If there could have been some sort of services to take travelers to their connecting flight, for cases of really short time window of course, it’d be extremely helpful.

Cons: Excellent

Pros: Crew was nice, despite multiple hoardings and time delays.

Cons: Plane was originally set to leave at 11:30 am, but was delayed until 3:00 pm for equipment. We boarded the plane at 3:00, the door was closed, and 30 minutes of waiting at the gate, where told to deplane, and the flight would leave at 5:06. There was another flight to San Diego, also delayed for hou

Pros: This plane has more space than larger plane, was more comfortable.

Cons: Out of the four frontier flights I’ve taken in the past six months each one has been delayed for some reason. First one was over an hour late and caused a majority to miss connecting flights. Today’s experience was not a whole lot different. First leg of the trip was behind schedule, second was delayed at the terminal for the “cleaning” of the aircraft. I will walk to my destination before ever flying with frontier again

Pros: The crew was nice, boarding was easy

Cons: The seats and space are horrible, it is almost impossible to stay seated during the duration of the flight because the seats are so uncomfortable and if you are taller like I am you will have no leg room and no support past your shoulders

Pros: I knew I was flying bare bones but I didn't really feel like it.. The leg room was awesome.

Cons: I paid for my seat because I didn't really realize I didn't have to. It should be made more clear about the seat purchasing procedure. I feel like I wasted money on two seats (to and from) because I don't care where I sit on the plane. Other customers I spoke with were also unclear and purchased seat. I'm sure this is not an intentional scam on your part so please fix it.

Pros: Better than most

Pros: It was clean, crew was friendly and the flight was easy.

Cons: It was a shortish flight. There wasn't really any entertainment options.

Pros: I was offered a upgrade for $50

Cons: My $50 upgrade did not cover my transfer flight from Seattle to Eugene. That's just messed up

Pros: The cheese plate was excellent. Sat in exit row seating so plenty of room.

Cons: Couldn't check my bags early even though all of the news outlets said to arrive early due to long lines at TSA.

Pros: Entertainment available excellent

Cons: Seating space seems to narrow

Pros: Equipment was adequate. I liked the on board emergency instructions!

Cons: Boarding was chaotic—no lines, just a mass of people all trying to get to the same place.The crew did their job but weren’t particularly friendly.
