Airline reviews

landed in panama it was in terminal one. We had to take a bus to terminal two for customs. Then back to terminal one. It was very frustrating. Then, on the way back from panama it was the same situation. We had to go back and forth between terminals to check in and drop our bags and then to board. When we were leaving, we had to wait in line for the boarding area and go through another gate security process. They told the bottles of water and coffee were bought while in line in the airport after we passed the main security. Ridiculous (and expensive). A much better communication system is needed.

Copa performed as expected for the amount of money I was willing to spend for the flight; it wasn’t exceptional but it was not bad in any way either. The crew was good; friendly and straightforward. The food was airplane food, so no expectations there and the entertainment was lacking but that was my fault for owning an IPhone with a charging port that’s not compatible with the rest of the world. I’d fly Copa again.

As usual, the flight with normal legroom was not very comfortable, but the second flight was much better because we had paid for extra legroom. It was very nice to check our bags without an extra fee.

Pros: "The seats in economy were confortable. The best thing was Copa gave us seats in the second line and my family traveled together."
Cons: "Coffe service could better the experience"
Cons: "Copa is trash . Doesn’t accolade passengers with hotels . They except people to wait in the airport for 14 hrs lay over when it’s their fault ! Straight trash . Poor 79 year old lady had to stay at the airport cause her family was 4 hours away ! Trash trash"
Cons: "This flight didn’t appear in AeroMexico’s system. We had to get our boarding passes in Mexico city, but our original departure was from YUL."
Pros: "good crew. great seats."
Cons: "I would like to have tv screens in flights from Bogota to Panama. No entertainment at all. But from Panama to Miami it was perfect."
Pros: "I thought we were going to die. There was tremendous turbulence. Crew did not advise if this was to be expected and if they are worried etc"
Cons: "Better communication other than out on your seat belts. My seat was fixed and I could not move it back either"
Pros: "The crew was excellent"
Cons: "My tailbone aches from the seat. Other friends who flew Copa Airline had the same experience. Friends on other airlines had no complaints. I need a donut cushion on the seat."
Cons: "Copa ground staff did not let us board citing some yellow fever vaccination card requirement. What Copa did not know that there are some exceptions (which they don’t know and of which we just found out) allowed by WHO which would have let us continue our trip to Managua. Will never, ever fly Copa again. Actually I advise everyone else to stay away from Copa."

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

Not sure why planes don't just board back passengers first.. also wifi connection could be beneficial and keeps passengers occupied

My experience with JetBlue was fantastic! The service was top-notch, the flight was smooth, and the staff were friendly and helpful. I would definitely fly with them again.

Non operational toilet, non operational charging outlets and my air didn’t work.

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items. Seats are uncomfortable. My butt was sore after the 1st hour of flying. Needs better cushioning at seats.

Check in machines at airport didn't work in both directions. Always needed manual intervention by an agent, which was very frustrating

My experience with Eva sir was good except the long walk in LA Lex, that was inconvenient for my age,

I think the food / snack service was very poor. tehy could have done better. Evrything else was great

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

Not have to pay for every single item to take a flight. Seating and delays sucked.

First time flying Frontier, I am not sure the Ala Carte menu of options is for me.

Terrible. Initially we were shocked by the outrageous baggage fees we needed to pay at check in for our so-called "discounted, economy flight" - we paid over $200 (!!) for one check-in and 2 carry-on bags - this felt like a real bait-and-switch" scam. Our flight from Phoenix to SFO was delayed by 4 hours. Multiple apparent causes (from needing to make space for other planes that were landing late to problem with cabins pressure system, and whatever...). After de-boarding and re-boarding we still waited at least an hour on a cramped, poorly ventilated plane before take-off. Seats were cramped, uncomfortable - did not recline at all. No water until we were flying for a while. No complimentary snacks. Upon arrival at SFO my luggage was sent upstairs to the check-in counter. The customer service person there refused to let me examine a bunch of bags that were sitting on a nearby cart because it was "behind the counter", rather made me wait until another attendant did an exhaustive and failed (?computer) search, came back and told me they were unable to locate my bag. I asked her to look on the cart, lo and behold, there was my bag just a few feet away! Missed my choir rehearsal that evening due to all of the delays. One more thing, a few days later my husband and I tested positive for Covid. Since we both are fully vaccinated, careful about masking and have never had Covid previously, we will never know, but suspect we may have acquired the infection during the prolonged wait on your poorly ventilated plane (person in the row in front of us was coughing). After registering a complaint, we received a measly $50 voucher for future flights. Needless to say we have no intention of flying with Frontier Airlines ever again.

My first time to fly Frontier and loved it! Boarding was super easy as we only had personal items. Crew was helpful and funny and the plane was clean. Pilot was also great at landing the plane smoothly.

Excellent crew. WE all know Frontier its a low cost airline but the travel time was about 30 minutes and the crew was phenomenal. I was with a group of 10 more and we are enjoy our flight. The only issue was in SJU waiting for the luggage.

The experience was terrible. The flight boarded late, then after leaving the gate the plane had had to return to the gate for fuel. After 2 hours on the plane, the flight was canceled. The reasons given for the cancelation didn't sound truthful. and different reasons were given. My 15 year old daughter was flying alone on this flight. When they all disembarked the plane she kept asking the crew what she was supposed to do. No one even gave her the courtesy of a response. No one. It took another 4.75 hrs to be out of customs and baggage. She was re-booked the following day. That flight departed 2 hours late. After all of that, they offered a measly $100 flight voucher with an expiry date of 3 months! All in all a terrible experience. We won't be using Frontier again in the future.

The only thing that may be concerning to others is the multiple notifications of a delayed flight. Then, with less than an hour before boarding, the flight was on time. The gate changed several times, leading to confusion.

We’ve been sitting waiting for a gate for 30 minutes without explanation. Several of the older flight attendants are very rude.

The flights were right on time. The issue that was the most difficult was the lack of legroom on the planes

There was an extra, unaccounted for passenger on the plane that delayed take off by 1.5 hours (which we boarded for 0.5 hours later than scheduled), ultimately was never found nor removed, then the plane diverted a storm and added another 0.5 hours to the flight, turning this 3.5 hour flight into a 6 hour flight.
