The flight was excellent and we appreciate that they ran the flight even though only 9 of us were on board!

The flight was excellent and we appreciate that they ran the flight even though only 9 of us were on board!

Excellent round trip from London Gatwick to Newquay Cornwall! Personable staff and crew, bags made it, flights on time. For me it was 5 stars.

For a small aircraft the choice of food and drinks was excellent compared to other ATR 72 operators. Checked in baggage as standard means easy boarding and disembarking for all.

I shall never book a budget airline flight ever again. Saturday morning flight to Belfast cancelled, rescheduled for following day, arriving 25 minutes before scheduled departure flight. I made the mistake of buying a non-flexible, non-refundable ticket options were so much more expensive. Alternative options offered by KAYAK did not come close in any way to my original booking; My first and last attempt to book a flight through Kayak.

Every flight on this airline is delayed, generally upto 2 hours for an internal flight. Very poor and absolute logistical disaster.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

Very good need to offer better choice of food for business

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Aer Lingus interior is not the cleanest. I've seen crumbs on the seat and wrappers on the floor when I boarded

All OK. Food, best bring your own. Even a BigMac will be better.

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

Total jobs worths over carry on bags, charged £96 extra for bags that were clearly hand luggage

3 hours delayed Don’t understand why when you have paid for ‘speedy boarding’ they call you forward to then make you stand fir another 20 minutes in a confined space before boarding the plane.

The pilot did everything possible to make up the 35 minute delay. His communications were honest, prompt and positive throughout.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Staff were very helpful. The free WiFi for messages was also very useful to keep in touch

Crew was more interested on looking at their phones than welcoming passengers during boarding.

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets
