The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Stuck on tarmac for two hours plus a 5.5 hour flight. Rude flight attendant. And no meals, not even for purchase!
I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.
The best airline I have ever travel , really good customer service, attention and service !!
Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely
Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.
Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.
Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.
Breakfast was not loaded at SFO due to catering company change. Seems like a major airline at a major hub would have thought of something else or warned passengers to pick up food before boarding a 3 hour flight.
Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.
Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.
The seats were not designed to comfortably see people in coach for more than 10 minutes
We flew TAP last October from Newark to Lisbon. The meal was bad. This flight had good food. Also, this flight was delayed. There were TAP employees waiting at Lisbon to make sure we made our connecting flight. I find the TAP website and app frustrating, but the service once we reached the airport was very good
Flight being delayed for 35 minutes had me lose the connection to my transport
Tap air Portugal was the best I will traveling again with u guys. Thank u.
The long wait at JFK made the trip horrible. Also not having enough buses when we deplaned was annoying
Flight was delayed on 6/20 to miss international connection. Next flight out was 24 hours later. Not acceptable.
Terrible! I had to cancel our flights due to my wife Carmen requiring an unexpected second cancer surgery. I first contacted orbitz about obtaining a credit due to medical interruption and orbitz directed me to TAP. I contacted TAP and the representative directed me back to orbitz and refused to even explain what TAP’s medical interruption policy was or how it worked—I wanted that information for a second call to orbitz. Terrible service at a particularly difficult time.
Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.
Terrible flight attendant attitude. Average 3-star hotel employee has better hospitality skills. Business class seats are literally a joke. TAP executives should ride business class in other airlines to develop some rudimentary sense of what business class is.
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
Crew was excellent, great customer service, checked luggage took 1 hour and a half to come out at the baggage claim, the only negative thing about the flight.
Horrible experience airline crew was unprofessional. Flight was delayed. Suit cases did not arrive. Never flying iberia again
People point to America as the model of late stage capitalism. My friends, airlines in america at least give you WiFi, and they haven’t quite smashed people into cardboard tv dinner trays yet. Iberia has mastered the tv dinner seat and WiFi is 20 euros. Be serious yall.
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!
The flight was delayed over 4 hours. Business class is just slightly upgraded economy.
Delayed and missed connections on leaving the states and returning Planes were old and small- very uncomfortable. Meals were good but very infrequent service for even water/drinks. No explanations for 3+ hour delay
Boarding on the buses isn’t efficient. Overall, it was great.
BEWARE!!! Iberia changes your seats at random. I paid for a window seat and they changed it to one in the middle aisle resting against the bathroom- can’t lean back + hear every flush. This on a 11 hour flight.. There were families that were broken up with separate seats all over the plane. Lots of upset passengers showing their seat confirmation to the besieged and helpless airline steward. Also, the gluten free meal was tasteless.
Iberia airlines was late on every flight I had. It was very difficult to communicate in English with iberia airlines and airport employees.
Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?
Enjoyable flight, helpful crew everything was organized to accommodate passengers.
I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.
We were never able to take this flight because our first flight from Austin to Dallas was cancelled.
The check-in of my luggage was terrible. When purchased my tickets, one luggage and one carry-on was part of the fight. My flight was switched from British to American Airline. During check-in of luggage at the airport, I was denied and had to pay extra $75. How do I get reimbursed for this extra luggage payment?
This was the second time on BA, food terrible, bathrooms gross,( granted, that was mostly due to the disgusting children urinating all over it)boarding was late and disorganized. No gate issued until last minute st Heathrow, bad system, caused undue stress. Seats were painful, that's what you get for traveling like a poor in economy, right BA? Should have been able to afford business or first class if you want to actually be able to walk upright without back pain after a trip.
As I said Al & AJ were absolutely the best and wow they should be recognized for their amazing service!
The delay was not communicated via text and the person who helped with check in also didn’t inform me about the delay. I ended up missing my connection and it was a waste of 5 hours. The crew didn’t mention there would be someone at the gate informing of if I would be rebooked and there was no signage. Overall a very poor experience. The British Airways app was also very buggy, and didn’t work. I will avoid flying with British Airways when possible.
Cancelled flight minutes before boarding. Rescheduled flight was two days later
The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!
