British Airways did not cancel our flight and would not give us a refund. They would only rebook our flight to several weeks later. We booked our flight months ago because the specific time we booked was convenient for us. Our new flight is not convenient for us and we don’t want to go to a country that we will have to be quarantined in. We were very disappointed.

Cons: I was in Business Class. The pillow appeared to be used on the flight from London to Antigua so i threw it on the floor in front of me. You would think with coronavirus it would be sealed like on American Airlines. No sandwiches or anything except some nuts and a small diet coke. I had to ask for a second one. It appears they only care about the people from London. Deplaning was from the middle door and it was a free for all. They have no idea about service well at least not in this leg.

Mediocre 2.0

Pros: The only positive with this experience was the gate agent(s) superior customer service. That being said they were stuck with dealing with a complete failure of United to provide guidance as to how the airline was going to deal with a technical issue with the plane. The flight was scheduled for a 7:00 AM departure, from what I could tell the flight finally left Portland around 4:00 PM. Because of extenuating circumstances myself and my traveling companion cancelled our entire trip. Given such a poor start we were unwilling to trust that any proposed alternative would be any better. In other words United seriously dropped the ball. They not only owe an apology to their customers, but also owe one to their hard working" contract" employees.

Cons: Communication. As I explained to United customer service, I find it incredible that the airline industry has built a business plan based on the misguided supposition that everything they do will go according to a best a case scenario, yet they appear to not have much of a plan when things don't work that way. Second, the idea that they have no proactive system to deal with technical issues a smaller destination. There are no mechanics/technicians stationed at places like Portland. I don't know what it cost them to have a revenue producing aircraft sit on the ground for 18-20 hours, not to mention the labor costs incurred trying to redirect 100 or so passengers. It seems to me that those numbers would probably go a long way towards paying to have a mechanic(s) on duty. As an aside, I paid retail for two first class round trip tickets. Given the circumstance I would like to see United refund those ticket prices in full, then and only then, will I consider using their services again.

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

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 the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes 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 can'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.

If you have more questions or if you have a bad price to report to us,
