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

They were super friendly bumped me up to exit row free of charge, All flight legs were on time

As always, Copa Airlines is great to fly on. The flights are always on time, the staff are pleasant and helpful and it's always a wonderful flying experience.

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.

I selected first class expecting excetional service. It was mediocre at best. The food service was cold, meal choices was poor and on one leg they did provide dessert. I did enjoy the lay day seat but the movies were old and nothing current. Boarding the plane is always hot. So boarding is quite warm until your in the air. I took a small personal air fan. Update the meals and movies.

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The seats were comfortable and we had leg room. Great entertainment.

The flight crew where really good. Better then the crew from BNE to SFO

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

2 hour delay due to equipment failure. No updates via the app and airport screens (which continued to show a departure time in the past). AA eventually switched planes and the new plane was not catered or cleaned correctly.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Could we please end the loud announcements about credit card offers on your flights? We are trying to sleep, work, watch videos, etc. and if we need a credit card, we will ask for one. Flying is already not what it used to be.

I would like the crew to talk LESS over the PA and specifically about credit card offers. I am trying to work, sleep, watch a movie and the PA was booming about a credit card offer. Could we go back to the days when the customer was more important than selling a credit card?

No enough space plus only allowing one laggage instead of two like other airlines.

It was good. But the gate team made me check my carry on when there was plenty of space for my luggage on the plane. Otherwise our trip was fine.

Deplaning was a mess, I sat in business (seats are horrible) and the front door had a problem so we had to deplane from the rear exit. The stairs were not tall enough to reach so there was a large step down from the plane to the top of the stairs.

Here we have another airline flying to Guatemala but doesn't have a plus or a less, just in the middle. Why? Well, first we don't have even free water Movie selection is poor Seats don't recline in some places Food selection is carb based Forgot to mention, customer service on the web is the worst. Good things; Very reliable on schedule Kind crew

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

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

Boarding, crew were excellent, food was ok and entertainment need to improve

Usb plugs for charging your phone does not work in every flight. uncomfortable chairs even in higher categories.

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

Horribly late because they had no crew!!! And then jet bridge didn’t work!! Then we arrived at a gate at lax miles away that we had to take a shuttle to a terminal!! I was over 3 hours late to getting the LA! Should have been here at 8:30 and at an appointment at 10:30 and arrived and left lax at 11 am!! Horrible experience!!!

Extra legroom with my upgrade bundle. Clean aircraft, on-time departure, early arrival. Good value for the price.

I didn't have a flight because of a ticking problem that was discovered at the airport at checkin for the initial flight of the round trip.

Even though the plane was delayed from the previous airport, the staff recognized this and kept us informed. The flight crew was absolutely awesome from on my flight from Ft. Meyers to AC. Great experience all around!

Flight was delayed would have liked it to have been on time. I didn't experience the food or entertainment but the boarding process was smooth and the flight crew worked well together and did a great job!

Not seat assigned because overbooking. We could go because some people decided to give their seats.

Spirit loves to pick and choose when to harass you about your personal item. I’ve flown numerous times with the same bag with no problem yet flying out of Orlando they forced me to pay $99 for a carry on and then ran out of overhead space. Do better!

For the price of the fare, there really isn’t much to complain about.

didn't order food on board. there's no way to hold a water botton on the way. otherwise it was a pleasant flight, thanks to the crew.

Even though there was a delay the crew was exceptional.
