30 minutes still don't have gate number, ask many people can't get answer.

30 minutes still don't have gate number, ask many people can't get answer.

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

My flight being automatically moved messed up my travel plans, and I had to quickly find an alternative mode of transportation. I couldn’t get a refund from any of the companies involved. Kayak, Ibiza, or Vueling. I am still unsure of how to settle my concern.

It was budget airline Veuling, even though we booked Iberia.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

Transportation from gate to airplane was poor we stayed in hot bus for 20 minute no vantilation

The crew were friendly and helpful. Iberia lost our luggage on arrival, Friday and we didn't get it until Sunday at 10:00 p.m. local Malaga time. I also paid $382.80 for seat assignments but two out out of the four were not together. Iberia mentioned that it was because the plane was delayed in Madrid before our flight began in LAX. They should compensate us half of my payment.

It was fortunate that the flight arrived in London in accordance with schedule, and the luggage was promptly transferred to the luggage carousel. However, I find it concerning that even minor issues in economy cabins are prevalent within the industry. American Airlines, in particular, appears to have the least legroom and feels more crowded due to the proximity of neighboring passengers. Additionally, the crew’s adherence to protocol is inconsistent. While they may enforce certain rules set by the FAA on a select few individuals, they often overlook numerous violations, such as failing to reset seat recline during landing.
