Flight got delayed; had to go through security three times.

Copa staff at PTY and one particular crew member were unhelpful & rude.

A lot things happened in this trip.The fly should be less stress.

Very strict carry on rules meant most of the plane had to gate check their luggage. As is often the case had things that were broken because of this, but I appreciated not being charged to gate check. Otherwise good flight and great crew once on the plane

Some of the Air hostesses are not that friendly. Need improvement

Cops Airlines is fantastic! The level of care and professionalism provided by the entire crew was top rate.

We had a great flight just wished they had a tv so we can see a movie that would of made my trip excellent.

horrible service, food was an embarrassment, no charging for cellphones, stay away

Great experience with a crew always thinking in the passenger

The flighr attandants were very rude they ignored me didnt offer me anything to drink throughoit the 4 hour flight i feel i was targeted and ignored because i was a darkskin latino man.

The chicken wrap was tiny ($13 for what looked like a 1/3 of a normal wrap?) and disgusting.

It was good experience this time. The flight was on time.

There was a delay with the plan which cause the flight to leave later and once arrived in Chicago there was another delay and some passengers missed their connecting flights

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

Overall, my last three trips on American Airlines have all been either delayed or "rescheduled" due to mechanical issues. At least on delay caused me to miss two possible connecting flights each later than the first. My last option for my last connection required the assistance of the onsite service desk (O'Hare Airport). The wait time for the service desk was such that it jeopardized getting booked on the last connecting flight available for the night. Suffice it to say, my latest experiences with American Airlines have caused me extensive loss of productive business and personal time and can therefore be classified as significantly less than satisfactory.

Waiting for gate in RDU for more than 20mins is crazy.

American Airlines was great and worked very hard to change my ticket so I could get an earlier, direct flight back to Dallas. However, I was informed that Kayak made mistakes with my itinerary and classified my ticket as desiring to be on the earlier flight instead of taking the necessary step of calling AA to get me on the standby list. This ended up keeping me from being added to the standby list and delayed me getting home by 6 hours. I am happy to discuss this further with Kayak so they can correct their procedures so this won't happen again.

Waited for oxygen tanks for 30 minutes after boarding was complete.

We flew in first class. The crew did not offer drinks before the flight took off, but they treated us well during the flight. The food was excellent. There was actually too much food served, but it was nice to have all the options.

Flight from CHI to PVD was delayed by over 20 hours.

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral and avianca lost my check in luggage

I upgraded to businesses class. Because of that the flight was comfortable.

Avianca has transitioned from full service legacy airline to "low cost" but has now became a strange hybrid (minimum leg space, started offering business class in domestic flights again, charges passenger for printing boarding pass, etc.). National and international coverage and destinations are really wide but service is not at its best

Provide free food and drinks on an international flight. Add updated head rests

Not good, tried to purchase a first class upgrade and they couldn’t get it done. Was super uncomfortable the whole time.

Boarding was late due to the company’s that cleaned the aircraft (very poorly done) and the catering company. The entertainment system was not working for this six hour flight, uncomfortable seats in business (barely any cushion or recline). The airline staff is very good but the planes are horrible and not well maintained.

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

No free snacks nor drinks on very short 30min flight. Entertainment system is over wifi to your own phone or tablet, which is good but often a show or movie just stops and refuses to continue
