Everything! Not sure if there's really anything that could make it any better

Everything! Not sure if there's really anything that could make it any better

Very quick trip from Southampton to Edinburgh Arrival a long way from baggage and up 3flights of stairs no lifts or escalators

Cons: "The flight was cancelled and we were asked to leave the departures lounge. There were no Logan Air ground staff actually working so we relied in the customer services desk at the airport to give us direction on what to do, and we were told that we would be eligible for compensation. I have now been told ( almost 2 months later) that the flight was only delayed and not cancelled so we are not getting a compensation payout to cover the huge additional cost I had to spend to fly another airline to get me to Aberdeen. Awful customer service, unreliable flights"

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.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

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.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

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

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Cardiff is a great airport but they pen you in at a gate way too small for passenger numbers. Called to the gate too soon and air conditioning was not in operation despite the heat. Cardiff should do better as a small relatively quiet regional airport.

Good, everything went straight forward and on time, I am satisfied

Perfect timing, perfect departure, lovely crew on the ground and in the air.

Good flight. Take off a little late but make up the time

Everything’s went straight forward, no issues, good service and friendly crew

Left on time and arrived on time both ways, thank you

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Cheap flights as you expect with Ryanair. I would take cheaper flights over entertainment and comfort for short haul travel. Main issue is usually delays at airports. In this case we landed roughly 2hr30 later than planned due to earlier delays with the plane. Not the worst I imagine

We each paid for 10kg checked in luggage. Flying out there were no issues sharing one case (20kg). Not so coming back. Additional £48 charge and unable to provide an explanation of why it was ok on one journey but not the other, or indeed what material difference it makes between 2x10kg cases vs 1x20kg case. Scam, and appalling from Ryanair.

Easy process and good flight experience The food good be better

Very bed boarding, there was overbooked and make a lot of problems and noises

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

I truly don't think there was anything that could have been better. How is that for an endorsement?! I'm a firm fan of BA now, with two flights in the past 2 months. Keep up the great work! And thank you!

New airport for me. A little confusing.bunable to use kiosk for boarding pass. Agent checking us in was professional but not very friendly.

Taking off and landing were smooth. I didn't have anything to complain about.

The flight as far as timings go was excellent. Unfortunately we ended up sat with someone on a night flight who had been drinking alcohol before boarding and BA staff were happily serving him more alcohol. He was very drunk which made our flight uncomfortable and awkward. My partner had this person lying on him whilst asleep. Alcohol should be served minimally. If there had been an emergency this person would not have been in a fit state to act accordingly.

The sad case is that BA is often late. I missed my connection outbound and then was rebooked in another biz class seat some 10 hours later. I opted to change to economy (no compensation refunded of course) that was only 5 hours later. On the return journey, once again changing planes was very challenging. This time we landed only a little bit late, but deplaning took a long time so the connection was very much in doubt. Some serious running and sweat later, I managed to make the connection but my luggage did not. No messages about the missing luggage, so I had to wait until the entire bag return process was over before seeking out an agent. There was only one and well over 50 passengers waiting to speaking with her. She was quite pleasant, but it took 1 hour and 45 minutes from touchdown to leaving the airport.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

BA charged me 70 euros for one bag on my return after having recognized my frequent flier status and charging me nothing for the same bag on the outbound. Their employees are not well trained and rules are inconsistently applied.

I couldn’t select my seat until I checked in at the airport. Extremely difficult to talk to a customer service representative. Also, the gate announcement doesn’t appear until less than an hour before boarding.
