The plane was at the gate for almost 2 hours due to the fuel tanks - apparently the engineers didn't know which tanks were refueled. Sounded a bit weird. I bill at $800 per hour - I think I should be compensated for my time.

Paying $275 to upgrade and experiencing one of worst flights and service I’ve travelled. No water supply for hot beverages, wash hands or brush teeth during eight hour international flight, not given special diet meal requested as crew unable to locate it, Entertainment monitor not working or housed in seat back correctly to adjust angle, remote handset buttons barely working to watch or make selections, unable to call cabin crew who did not visit through cabin for approximately two and half hours as ‘assumed most passengers were sleeping’, no wine choice only Sauvignon blanc and I wanted Chardonnay so had nothing. Breakfast ‘special diet request’ meal was cold hard bagel with colourful lump of cream cheese, which seemed to be what everyone else had. No orange juice, grapefruit that can’t take medication with, so had nothing to drink except allotted splash of water into small paper cup. Dreadful journey

Supposed to leave Boston at 9:30 pm, instead 1:30 am. It was said they knew this the day before and sent emails to passengers. No one who I spoke to, including myself, got one. Aer Lingus hired another carrier to do this flight—plane, crew —no Aer Lingus personnel. Everyone was nice, but. Had made arrangement for early morning checkin. Got to the hotel SO late that they waved a fee and had our room ready. Was going to sightsee the first afternoon—basically lost a day of seeing Dublin.

First experience flying business class -- and Aer Lingus has it down to a science! Great food (maybe too much actually!), friendly attendants, great service -- and the most wonderful pods that allow you to lay out flat for a snooze, complete with duvets and pillows.

The few staff that were working at 05.30 did their best to cope with no electronic booths.

There was checkin system upgrade that meant there were no electronic check-in. Flybe knew there would be long queues but did not lay on extra staff to deal with it. Not good management.

We left on time and arrived earlier than expected.

Nothing. It was great. The only reason that I gave 1 star for entertainment is because tgere waan't any entertainment on board. But that was fine. I had a book to read.

I liked that the seats were very comfortable and had enough space.

I didn’t like that I had to go through security twice once upon arrival and once in London. i also wish I would have booked a different airline so I could have had a direct flight. That wasn’t a problem with this airline though, just my negligence with research.

Absolutely nothing

Traveling for important business trip. Flight got canceled for “operational issues” and I Never received a notification from the airline or booking agency. I was told I couldn’t get a flight until 24-48 hours later. There were flights available through other airlines, so I asked if they could get me on one of those flights. I then sat on hold for 45 mins to be told that the airline wasn’t responding and the only thing they could do is refund me. I ended up purchasing a new round trip airfare 4 hours before departure which cost me $1000 more than what I paid for my original flights. I was experiencing a lot of anxiety and stress during this period again with no help from the agents. I expect someone to get back to me regarding this and offer some options on how to make this situation right.

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
