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!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

As four hour wait with no explanation as to why the delay Very unacceptable

Excellent long haul experience really enjoyed using Dublin pre-immigration

Nice easy flight. Crew was very nice and of all the times I have bought a seat for my guitar - this was the easiest. They were prepared and no problems at all.

Air Lingus flights were delayed on each of the three flights we took. Not a very good , and organized airline.

Flight was ontime, clean, staff was friendly - there was turbulence but can’t avoid that (it’s a flight 😉)! The staff were attentive but would be nice if Aerlingus didn’t charge for coffee ☺️ but overall I enjoyed my flight experience and will travel with them again (Ireland’s Four star airline

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

I didn't like. The seats and the floor were very dirty and it is not the first time

Unfortunately didn't realise how far away Frankfurt Hahn airport is from Frankfurt the city. Outbound flight was delayed by 2.5 hours and no communication at airport, just a whisper emknating through the packed crowd ready to board at the gate as someone read out an email they had received. All rather poor and pathetic

Pros: "Cheap, saved me when I was in a pinch, and easy check in. I loved being able to check in on the app and check my own bag!"
Cons: "It was difficult to understand what the flight attendants were saying over the intercom. Between the masks and the intercom, nothing came across well. Please continue to wear masks, but perhaps find a clearer way to communicate for those of us that are hard of hearing. I was too embarrassed to say “what!?” 84 times. It’s not their fault."
Pros: "flight late so crew dismissive wanting to get people on board, during flight was ok"
Cons: "smile it helps"

The crew on this flight were attentive, efficient and friendly. It really made for an enjoyable flight.

They canceled my flight , they put me on a different flight that was delayed and the connection was lost . They lost my luggage. And now I’m stuck with any of my belongings.

4 hour technical delay. Cancelled second meal. Crew and flight were great.

British Airways canceled our plane and gave us a new flight scheduled to leave in only three hours, so we had to drop everything and rush to the airport. The new itinerary only left us a one hour layover in Madrid, which was too short because the plane landed late and so we missed our connecting flight. We were then booked onto a flight scheduled to take off 8 hours later, and were not given any compensation or remedial measures.

It took over an hour to check in my bag a there was just one person at the counter. Security lines for business class also took a while. Although I reported 3 hours before my flight I made it to the gate 20 mins before boarding. To add to that jewelry was removed from my checked in baggage. I am submitting a separate complaint to Mumbai airport for that.

Everything was great except for online checkin. That was through BA- glitchy and needed help on seat choice in person at the airport (and the staff were fantastic). Unclear if the problem is due to booking lower fare thru kayak vs directly with Finnair or BA but seems to be the norm.

Seat layout, flight/club attendant service, food variety and quality could have been better. Business class Standard is visibly low compared with 6 other airlines that we have traveled for the past two years.

Despite many attempts to work out a change, neither British Airways nor Kayak nor Chatdeal would allow us to cancel or change this flight so we lost all of the payments when we were not able to fly. Absolutely terrible customer service. We will never use either of the services again.

It said that there was wifi. During the flight there was no wifi and while waiting at the gate the phone services already got cut off so I wasn’t able to say I am taxiing from the gate to my husband. This left me with an uncomfortable feeling. So I was waiting on the WiFi connection during flight and that never happened.

The check at Accra was very bad . I had to be in the queue for solid two hours simple because your staff were pushing people and lifting the balustrade for them to jump the queue. This situation made us very made with your Accra check in crew. I have video of what I am putting across and I am happy I have the opportunity now.I can send the video to you if you are ready to punish those involved.

We bought tickets for £30 from kayak but we paid £55 for check in to rayan , they slaught us

Flight was delayed so long we missed our second flight. Entire trip had to be cancelled. Ryanair refused to help us.

Stanton airport is outdated, pure equiped, airport. Fire alarms, power outages is a common routine, wich result ir flights delay , additional money spending and huge gathering of people in airport wich is unsafe.

After you made us check-in I tried to add a suitcase in the internet and also to get help by chet. Nothing work and we pay 60 pounds at Airport. Comper to Easyjet to do the same, was easy and customer friendly.

Boarding was like being hoarded like cattle, all penned in in an area way to small

I missed the flight from Manchester to Dublin because of poor informations from Aer Lingus and the airport, no possibility to check in online, they don't respond to phone calls, I had to buy another tickets to enable me travel to Dublin from Manchester. I want my money to refund.

I were there 20min before departure and they didn’t let me on the board with 5 other people, after all they admitted it was their(Ryanair) fault.
