Fast and efficient boarding, pleasant flight with plenty of leg room in economy delight. Food was good and the afternoon tea was a nice touch. Was a little delayed in Canada due to CBSA checking all passengers at the jet bridge but otherwise great flight

Fast and efficient boarding, pleasant flight with plenty of leg room in economy delight. Food was good and the afternoon tea was a nice touch. Was a little delayed in Canada due to CBSA checking all passengers at the jet bridge but otherwise great flight

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

Paid relatively a lot of money for a not comfortable seat. I would not take this service again until seating is improved. Food also not up to standard for price paid.

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

JetBlue is always consistent and great, the food is limited in selection, but at least you can grab as much as you want on snacks and drinks at the Blue Locker.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

Flight was on time arrived at the destination 10min early they kept in touch via email

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 !!!!

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.

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.

Wifi screens were great. Both flights were delayed, spending all day flying home and then getting home at 3am ruins the next day also.

Poor boarding service and luggage took forever to be delivered!

It was a smooth trip, everything ok. The crew were so nice and professionals. The only thing that I didn't like was the tiny dinner table of the plane but I guess it's not the crew fault. Overall I recomend flying Iberia.

There was confusion over the electric wheelchair. Though it was categorized and double checked at checking the gate seemed confused by the chair.

Boarding was a mad rush as people still had issues with boarding passes and groups 3- 7 were asked to board when travelers were still stuck behind the document check. Food was one of the worst I’ve ever had in an Economy flight. The crew was very friendly though

We were delayed 2 hours because the crew was late. They need better planning by the crew, we had to sit in uncomfortable seats waiting for them.

Difficulty to check in online, but well handled at the airport. Flight delay was unfortunate. Crew was adequate but not what we have usually experienced from BA. Seat was not comfortable.

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

I’m very mad because I paid an extra $105 to change seats to an exit row with more leg room. The app clearly showed a gap in between the seats in the row I changed my seat to and I paid for it. When I boarded the plane, it wasn’t an exit row seat and no more room than my original seat. I feel like I was ripped off $105.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

okay, will recommend from PR to Madrid, faster turn around

My baggage (1) didn’t arrive with me. I am waiting for it.

Terrible we had to wait out in the cold for transfer bus to take us to the plane. Once we finally got on the plane seat had no cushioning not comfortable at all. Food was overcooked and dried out. I was skipped over when they served drinks I had to call them back to give me a drink with my food. Overall terrible experience this time. I have used BA before and never experienced service like this before. If this keeps up I will look for other options

Heathrow Airport - a nightmare. BA flight, expensive for no other reason than the flight was full. So they will at least be happy. Departed late. Aircrew got the job done, but attendant responded to my question regarding purchase currency sarcastically. Comfort OK entertainment system OK, Landing time ahead slightly so well done pilot. Overall mediocre to OK but I'll fly from Gatwick next time!

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

My only issue with my flight to Jersey was that the Gate wasn't announced until shortly before boarding, otherwise all went well even with how busy Heathrow was. I appreciate British Airways staff's politeness, hospitality and positive energy.

Boarding was smooth and speedy. Pilot explained route and that even though we taxied a little later than planned a tail wind meant we landed earlier than expected.

Cabin crew was very good. No wifi and no doors to the suites

Very timly. Great service !!! Pick up after meals can be swifter.

Even though I we were flying Business, my wife was in a wheelchair and the lady in the counter told the airport employee that he had to make the line (this was a first for us). There was only snacks and a heavier option to sell. The staff in the plane was great.

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

The usb plugs for charging your phone didn’t work, the seats were coarse and hard. Not very comfortable. No inflight WiFi

why did we have to go through security mid flight

Flight to Bogotá delayed by 3 h Missed connection from Bogotá to Guayaquil. Avianca unable to bring us to Baltra on time Overall delay 36h. We missed boat departure from galagos. Overall 10 day trip needed to be cancelled. Avianca was completely un-professional.

A few years ago long flights 6 hours or so used to have video screens and they offered ear phones. The food cart used to come and drinks. Now absolutely nothing. Avianca is as bad as Spirit Airlines. Avianca will now be my last choice when booking my next flight.

Worst airline , charge for everything even for water, seat space is very bad

My fly was cancelled so i run to the airport and fight for my fly Thank god at the end was good

Avianca: you pay for a high-end flight and you fly like a low (very low) cost!

Horrible service. Flight was delayed and the don't even offer eatwr
