Airline reviews

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

Captain and Crew were excellent. The Boeing 737-800 was showing its age. In flight entertainment system was sluggish and my Business Class seat on the outbound flight had some mechanical issues. Only real problem was the location of the Gate in Panama PTY. It was a 40 minute hike from Security to the Gate. There should have been some sort of warning about the distance.

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.

This was my first time flying Copa but I'll definitely be back! Great service, professional agents, and delicious food for a fair price. Thanks for a great trip!

Horrible experience from start to end. Copa costumer service is non existent. They treat you bad. Everybody tells you different information. We didn’t received our luggage in the 1 day stop we did even we they said if was not going to be a problem. They didn’t respect the seats that we had and spread our family leaving in between of two big people who didn’t leave any space for me and crush me from side to side. I’ll never recommend Copa to anybody.

No cumpli mencionado trayecto por reasignacion de Copa Pero extraviaron mis maletas por su culpa

I was fortunate enough to have an entire row to myself and that was the highlight. Unfortunately, the flight was really turbulent which had no impact on how effective the crew was. However, I am disabled and should have boarded the flight first, but that wasn't the case. They also decided to take my bag at the gate because I had one too many and upon my picking it up at JFK it along with my rollator had been damaged. I am a vegan so the didn't have a proper meal for me and I was unable to view the entertainment because I didn't receive a set of headphones and if I needed to supply my own I wasn't made aware of that either. The crew was great, but overall everything was pretty lackluster.

LOCKED MY BAG WITHOUT CONSENT. Had to have my zippers cut upon arrival in Costa Rica.

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: "Sure. I had booked a two week vacation in Brazil. All hotels, car rental and guides booked. Copa changed my fligjt at the last minute and out of the 14 days vacatipn I had in Brazil, they would have me spend 6 days in Panama City!!! Lost of small fortune with hotels, car rentals amd had to buy another ticket with Latam. They are a scam!!"
Cons: "Due the COVID-19 El Salvador closed its boarders, leaving me unable to fly. I have sent two emails, called and spoke to a customer service representative who treated me unprofessionally and rude. After that I have been calling numerous times with a wait of over 25 minutes each time and I still have to answer from you as a company. I am extremely disappointed and want an answer soon."

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

Easy peasy. Crew was great. Take-off and landing nice anc chill (good job by the pilot). Thank you UA!

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Because I can’t stand very long in one place, I was allowed to reword.

Horrible people at the gate, they force me to check in my carry on, even thought no one behind me has to do it. I had to get out of the airport in NY to get my bag and go thru security again on my way to Honk Kong. The worst part is the employee threatened me with loosing the flights if don’t comply.

Delayed flight, few announcements with information, no comps, cluster f boarding because zones weren’t spread out and announced loud and repeatedly, staff did their job -nothing more nothing less, annoying kids were speaking and kicking the heck out of the back of my seat and parents weren’t willing to parent… so another typical day of air travel in the US.,

Flight was delayed until Next day as crew timed out

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

I was able to get on standby with relative ease

6 plus hour delay with no explanation. No wheelchairs to transport us on arrival. Very disappointed.

Me and my husband experienced very bad in American Airlines. We missed our flight going to Doha. The American Airlines was delayed we arrived already 10:27pm. Supposed to be 9:40 pm. So what they did they rebooked our flight and they gave us a hotel. When we arrived at the hotel the front desk said it was fully booked already. Oh my gosh! I said why did you accept the booking if it's fully booked. The guy said that's American Airlines they just book even it's already full. That's 2am already, we have nothing to do so, we decided to go another hotel. We pay the room, food and taxi. Pls give an action on this matter. Refund our expenses and give us more compensation. Not only our room, food, taxi but also our efforts, tiredness looking for a room that can accommodate us.

Flight kept delayed from morning to late afternoon so I had to make other arrangements

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

My wife and I are both handicapped and at boarding they upgraded us to a seat closer to the front rather than all the way towards the back. Much appreciated.

Spirit canceled the flight in March and never notified me!

Seats suck, not enough room, overcrowded planes, hectic situation all together.

I do not like the customer service, I had an emergency and needed to cancel a pet reservation right after I had booked it and they would not do anything but issue a credit. I haven't flown in years as I have 7 kids and don't have spare time. I want my $125 back on my card please

I paid just under 200 for flight and luggage, then paid 200 to change the flight, then paid 100 for a carry on. Then the cancelled the flight. Of the 500 I spent they refunded 250. I bought a delta flight for 270 never flew with spirit, but spirit kept 250, not even refunding the 100 for the carry on though they cancelled the flight (for weather on a day with only a slight rain ).

Flight attendants heavily pushed their affinity credit card. Very annoying

On time and fast. Overall it was a pleasant experience.

Didn't like anything!! Horrible flight. Small seating area and hard seats. Butt was sore after 2 hour flight to Seattle No entertainment or free refreshments No wifi or USB charging receptacles to charge phone entoute like other airliners Luggage rates were 3 times as much as competitors. Difficult to navigate online luggue process to pre pay before flight Overall bad experience WILL NEVER RIDE OR RECOMMEND FRONTIER TO FRIENDS OR FAMILY MEMBERS!!! THIS IS A SHAME!! MOST MESERIBLE FLIGHT OF MY LIFE!! AND I THOUGHT SPIRIT WAS 👎 YOU GOT THEM BEAD HANDS DOWN!!

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

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

Terrible. Seats are bad and the baggage policy is inconsistent

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights

They lost my baggage on my connection flight, it’s been 24 hours since I put my claim in and still no update on my bags.

It’s a cheap airline. I wish they had better seats.

The only issues had were outside of Frontier’s control or weren’t expected. It was a two hour flight they completed fast. We landed almost an hour ahead of schedule. The issues with no entertainment or food weren’t issues since there was no expectations. The issue of the loud or crying babies was outside of frontiers control.

Seats are cramped and very uncomfortable. You have to pay for everything and it is too expensive.

Smooth process and flight. My favorite kind. Uneventful and on-time!
