Boarding gate at LAX was too crowded—two gates next to one another

On time departure and early arrival. Flight attendant very nice.

The business class layout of chairs was weired. You are sitting directly across stranger.,

The SFO Lounge crew were amazing. The bartender Faris was great. Thanks!

Friendly crew is the only nice thing. Seats uncomfortable. Food and snacks horrible. Movies were the same as the first 10 hour flight two weeks before

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

We left at 1030 am pacific from LA and supposed to land at 7 pm Eastern in NY. They made a detour, stopped in Philadelphia and didn’t land till 1130 PM Eastern!!! Worst flight experience with no pilot communication with no explanation as to what was going on. Everyone was very frustrated to say the least.

I cancelled my ticket less than 24 hours deadline but I didn’t get refunded.

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.

Service was good , communication and emails were in Spanish though I booked in English , end up figuring it out but also flight was partnered with air maroc and I had to call them to check on not Iberea doesn’t make sense

In general, I've had excellent experiences with Iberia flights and will continue to use them. In this last flight there were two things that didn't go right. I didn't get the kosher meal I had pre-requested when I had checked in on-line. Things worked out OK as we ended up eating the fish and vegetarian choices, which were really good. The other issue was that some movies for me and my wife started fine but after 8-12 minutes the content just switched to something else. The flight attendant reset our entertainment systems, but the problem persisted. We ended up choosing other movies/TV shows that did work fine.

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Really like the idea experience on this airline I will use again

The pilot was professional and very good. The flight crew, very young and often looked flustered and overwhelmed. The seats were among the most uncomfortable in the air. The boarding somewhat chaotic. The price reasonable. Overall it was an average budget airline experience...although Iberia is not a budget airline. I fear if Iberia doesn't up it's game customers like us will go elsewhere.

Bad weather Excelent pilot Spoke British 😆on time seats small ad expected in a discount airline

It wasn’t great because the third-party from Kayak there was just no information about how to check in with Vueling. And the purchase of the ticket from under pricer just made everything really difficult. I’m unlikely to use Kayak again for these reasons.

It was fine, older plane with limited entertainment, otherwise fine.
