The flight was late. Please do not delay next time.

I couldn't travel, now I can't get a refund and to change the date I have to pay an absurd fine.

Boarding was confusing with a delayed flight because there was no English translation

Horrible the worst airlines I have ever flown. Cancelled flight with no choices and when contacted them they were not helpful

Bought a ticket that included a bag and they still charged me to check it in, latam is the worst airline.

Lost ,y connection due to a mechanical delay, huge line to get new connection and vouchers

It’s a delta flight operated by LATAM. The whole ticket sale is a mess, delta changed my flight but didn’t update it in LATAM system, I couldn’t get my boarding pass, it took me hours to resolve this issue with delta. I had to change my travel plan. No apology from Delta even though it’s their fault.

Boarding was done by woman who insisted on strict standing in line policy; food was ok; entertainment minimal

I was in the last row and they sent me to check in my luggage last minute after boarding. I had to go through the crowd.

Our flight was cancelled and it took them 5 hours to reschedule and the next morning they said we still didn’t have a new ticket.

Boarding an international flight via several sets of stairs and shuttle busses to the tarmac even when multiple jet-bridges were empty at Madrid airport (the hub for Iberia) was not pleasant. I was fine, but a lot of elderly folks and families with kids were struggling. A bad way to start a flight. Business class seats were nice, although not cleaned well from the prior flight.

Delayed first flight Geneva Madrid.. We didn’t miss our 2nd flight only because the 2nd flight Madrid Dallas was 1h delayed. However we did end up missing the 3rd leg Dallas Austin. Luggage didn’t show up in Dallas. So we re missing 2 suit cases. Customer service sent us to a hotel in Dallas. Only one room booked for 5!! Pretty bad experience overall. I won’t book a flight on Iberia in the future

Horrible experience airline crew was unprofessional. Flight was delayed. Suit cases did not arrive. Never flying iberia again

Iberia lost my bag, said they found it in another country, said they sent it to me, but never did. Went my whole trip without my stuff, but expecting it to show up because that’s what they said would happen. Their communication sucks, their website sucks, and to top it all off, their seats are small and uncomfortable. They’re bad at their jobs and they should feel bad about themselves. Do not even get me started on the flight home. AVOID!

Boarding was 2 1/2 late no explanation Captain said he did not know why, but he rested at home for an extra couple of hours. Food was edible, Nothing more.

Iberia airlines was late on every flight I had. It was very difficult to communicate in English with iberia airlines and airport employees.

Paid for my seat 4 months ago. Did not pay the extra for specific seat assignment ( never have and never was a problem). Could not electronically check in (found out it was due to overbooking and that unassigned seats get bumped first - never happened to me before). Luckily, did make the flight. Very stressful - would have been extremely disruptive for my travel plans. UK Visa - never notified by Kayak or BA that a visa was required. Had to spend 15 minutes to download and complete app at the flight counter and pay $25, and was told they would let me know in 3 days if I would get it (flight landing in 10 hours from when I completed app). Luckily, visa was approved before landing. Unnecessary stress created here. Food - main meal, curry chicken barely palatable with unrecognizable vegetable. Desert cup, cheesecake, also barely palatable. Salad cup was good. Small water offered only 3 times (before main meal, at main meal, at morning snack) - not nearly enough for long flight.

From boarding, to attention in flight, I couldn’t fault it.

Not having to check carry on bags when plane wasn’t full. (The told us it was)

Service and food were excellent, could have been more info in English.

The seats were uncomfortable and barely reclined at all. Very little leg room despite being business class. The crew was friendly and the food was good. Had to use my own phone for in-flight entertainment.

Avianca is not what it used to be. So disappointing

i think the flight was late because they were so strict about measuring everyone's personal items to try and charge them $119. It was really petty and made us late.

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.

The seats were very uncomfortable. I would have upgrade or got different flight if I knew. I usually sleep in the plane but I couldn’t sleep at all. Very uncomfortable. Also no food or drink everything was to purchase, and that’s u usual for international flight.

We did not know about the bag fees until check in. They are way too high. It’s insane. We also had a huge delay and everything costed extra which was very annoying.

Boarding was somewhat confusing in that the wrong messages were being displayed at the gate. It was somewhat annoying that I got off one flight and straight onto another (from the same gate), but in between they re-checked my hand luggage and made me get rid of my water (which they charge for on the plane). I was sitting in their 'Plus' seating, but the leg room was still too small to be able to sit square. The food options on the flights are pretty cheap quality (but not price). They got me from 'A' to 'B' on-time and for a relatively good price, but the experience itself was below average.

So so, you feel like you have to pay for everything each time

please see previous response; it covers the whole travel trajectory.

I paid over $200 for seat selection for these flights and I was still stuck on long international flights in seats that do not recline and do not have the head support cushion. At this point basically all airlines have those for all seats, and this really took me by surprise and made me not ever want to travel on Avianca. The Kayak agent who called me for the seat selection (Donovan) was courteous, but it seems the system for this doesn't work. I was offered seat selection, for the $200+, but without being able to see what I was selecting, with no guarantee where I'd be...and then I still ended up in terrible seats. On my way to, and especially after, a very intense business trip, the seat situation really soured my experience.
