Al llamar a Iberia(horas antes de nuestro vuelo)para informarles que por llegar a Venecia a bordo de un crucero y este no poder entrar a puerto en hora por motivos de la neblina y por esa razon no poder llegar en tiempo nosotros al vuelo,nos dijeron que no podiamos volar con ellos desde el vuelo de Madrid al otro dia a Miami y solo nos ofrecieron otro vuelo para 3 dias despues y con un precio bastante alto,conclusion que siendo una compania tan reconocida poco nos ayudaron, por no decir practicamente en nada,

Great moives and enteratinment system. Comfy seat. attentive staff on board. Also minimal annoucements, which i love because i don't like to be disturbed in my sleep to hear about the weather.

Was stuck on plane for 3 hours before they had to cancel it due to computer issues. Missed connenction flight ( 27 hour delay for connecting flight) with them as well as a result, had to stay 2 extra nights (in great accommodation they provided, at least) had minimal information about what to do in the morning (almost missed the bus to the airport because they only had a little sign noting it) Overall they took care of us from the delays, but I still missed a day and a half of work because of it.

Very uncomfortable, no refreshments. Everyone on the flight was suprised to find that food and drink cost money. The entire flight, the crew was selling something and you could not pass in aisle or even use toilet for half the fight. No entertainmrnt on a flight of 4.5 hrs and this was not supposed to be a low cost flight.

We were unable to find a row of seats to more comfortably facilitate traveling with a baby and a toddler as seats that should have had a cot or extra seating didn't have the cot and were sold out for an additional fee before we had the chance to. Discussing this with the staff at check0in and at the gate, made no difference as they had no knowledge of what was available on that particular flight. Every time I fly with American I'm reminded of why I don't like the airline and I will do my best to avoid them moving forward regardless of competitive ticket pricing.

I booked the seats with extra room - really glad I did. The food wasn't bad, the entertainment system worked. I definitely prefer the Virgin Atlantic entertainment system, but I fly AA fairly often and will continue to.

The airport check-in was absolutely terrible. We were in line so long that an employee came up to us and said "I can't believe you're still here." Neither could I. We get to the airport at least three hours early because of stuff like this, but the incredibly slow line and unorganized way of handling it ate any of the time I'd looked so forward spending at Heathrow (I love hitting Boots etc).

That they actually gave a meal.

Main course of chicken and rice was clearly on the small size for a 10+ hour flight. The chicken was in some vague sweet and sour sauce. It was a good thing that I had bought sandwiches before boarding. Return flight LHR to LAX was on BA and the main course of chicken and mashed potatoes was substantially larger and tastier.

The flight to and from Los Angeles was operated by British Airways and was on one of their Airbus fleet. Boarding was completed efficiently and with ease. I sat on the upper deck and was very comfortable in comparison to other major airlines previously used for this particular flight. The plane was very clean and the crew were outstanding. Nothing appeared to be too much trouble for crew, and they were ready with beverages, including tea and coffee, and snacks throughout the flight. In flight entertainment was good. All in all very pleasant flight to and from the U K.

Crew, ground and flight crew, were all so friendly and accommodating. Great access to free snacks/drinks, but the best was the seats with the footrests that lift all the way up to form a couch, even for those of us who aren't able to fly business class, but are frequent flyers.

The video system wasn't as good as say, Virgin or B.A., but it's such a small issue, compared to the superior comfort of coach in Air New Zealand to the other steerage-like coach classes.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an email and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
