Airline reviews

Pros: "It was short and with friendly staff."
Cons: "No complimentary refreshments."

Cons: "Best flight I have ever been on"

Cons: "Late - again!"

Pros: "Comfortable seats"
Cons: "Slow boarding"

Cons: "2 hour delay on an hour flight"

Pros: "When I finally settled into my seat on the British Airline and that Hostess came around and offered me a couple of free drinks that was the best thing that happened to me all day."
Cons: "For an older couple like us did not like having to climb the steps up into the Plane and being out in the rain did not help. However that was not the worst part of the arrangement between getting off the Aer Lingus plane and with so little time to reach the gate for our BA flight to Denver it was a total disaster. Due to a minor problem my wife had with her foot I had asked for a wheel-chair to be available when we got off the plane at Heatrow. Good job that I did because with out their help we would never have made it in time for your flight to Denver. Between up and down in elevators, running along the corridors, in and out of a bus and I myself trying to catch up with those poor attendants. I was sorry that I did not get a second wheel chair for my self. Only for the flight was delayed by about 20 minutes we would have missed the flight. Who ever was responsible for making the arrangements of just allowing a time of 1 hour and 10 minutes between flights needs to figure out a better time schedule before people of our age ends up getting stressed out and end up with a heart attack. Very stressful indeed, believe I will never let this happen to me again. Fly/Us you need to fix this."

Cons: "While I didn't have to check my bag on the first longer flight, I did have to check it on the connecting flight which delayed me somewhat in getting into the city of London. Not awful, but strange... Free-for-all when boarding, not nearly as organized as it was at JFK."

Pros: "The efficient flight but no drinks or snacks w/o purchase"

Pros: "Crew polite. Seats comfy."
Cons: "One person checking boarding cards at gate led to a ridiculously long queue for a nearly full flight and made it late getting us all on the plane and passengers were getting annoyed. Then whatever machinery Aer Lingus use to push the plane back from the gate actually got stuck on the plane cone leading to another delay. Knock on was we were made to wait for a take off slot and made to wait for a landing slot at Heathrow so late arriving."

Pros: "Reilly dolly"

Pros: "Quick and efficient."
Cons: "N/A"

Pros: "Efficient staff and timely I would book again for sure"

Cons: "The problem I had is that this was not a British Airways flight, nor were my flights to Dublin. I was not aware of this. When I checked in online I was allowed to check in with British Airways, so I had no idea that this was an Aer Lingus flight, which is in a different terminal with a different flight number. My phone didn't work in Ireland so it was extremely difficult figuring out where I should have been. If I was on a different airline that is affiliated with British Airways, and I booked through British Airways, there should be some way of looking up where I should be going. Also, any emails about my trip should have told me which airline I was on. I fly often, and often to other countries. This was the most confusing and difficult flying experience (the entire trip -- getting to and from Dublin) I have ever had."

Pros: "Friendly crew."
Cons: "Having to use steps at Cork airport . The cost of tea served in a disposable cup is too expensive."

Cons: "I'm soooo upset about the service after my flight canceled. 1.the staff ignored me when I asked if I could have a VIP to rebook my tickets earlier because my mom got cancel and was going to do the surge . But he went away and never came back, no any response of YES or NO. 2.I don't know why the airline company still need 11 hours to rebook the tickets with all our flight information and our passport liscen numbers already , making us waiting till 3 am at the airport. 3. I asked my boyfriend to talk to the staff on phone, and the staff told my BF that he didn't know my English was not good. I said to him loudly that I had told him , but the manager besides said "don't shout at my staff"to me, even without asking me what happened . I don't think that was a good attitude for the service department, especially to a foreigner. My email address is Chentongtong@wku.edu.cn"

Pros: "Preferential seating, though I had to pay for it."
Cons: "Having to pay for a cup of tea."

Pros: "Comfortable Clean"
Cons: "Food/drinks a little expensive"

Pros: "Very polite and helpful."
Cons: "Unknown"

Pros: "The planes were comfortable and the online and airport check-in process goes smoothly."
Cons: "Not even water is available to passengers. And flight attendants must shill to SELL food perfumes and merchandise during the entire flight. It seemed very unseemly that professional flight attendants were forced to behave in such an unprofessional manner. Sell, sell, sell is their job on Aer Lingus."

Pros: "The fact that there was no one sitting by me was fab. Through man on priority check in desk was very helpful getting me the assistance I needed"
Cons: "More choice of meal. Getting special.assistance.upon arrival at.Istanbul airport first outbound flight was hard. I nearly fainted as I had to stand for so long."

Pros: "Helpful and Friendly Crew. Did their best to help during the delay. Able to take hand baggage on board (unlike our kid journey when forced to check it in at the gate)"

Cons: "Everything"

Pros: "The aircraft seemed new or renovated and it was fairly clean."
Cons: "The crew was talking with a passenger at the end of the corridor while laughing very loud. This caused many passengers to wake up from their sleep or just disturb them from their reading.

Pros: "Good service and crew."
Cons: "Seats were very very narrow."

Pros: "Great relaxing"

Pros: "Nice staff."

Pros: "we buy the tickets from kayak and reconfirmed with British Airways is that we allowed to have one suitcase of 23 kilo checked in for each person . would get to their products and we paid 180 US dollars for the read suitcases we have . I didn’t mention kayak to give me the 180 us dollar back"
Cons: "we buy the tickets from kayak and reconfirmed with British Airways is that we allowed to have one suitcase of 23 kilo checked in for each person . would get to their products and we paid 180 US dollars for the read suitcases we have .

Pros: "On time"
Cons: "Couldnt pick seat after checkin. They put me in the middle in the back row even though there were better seats left empty right next to me. baggage would have cost 100 pounds to check. Flight was not exactly cheap at 200 pounds. Will just fly the budget airline next time over british air since. I expect better accomodation for these prices."

Pros: "Flight was on time and boarded well"
Cons: "This was a codeshare with Iberia and the seats were incredibly close with barely room to fit a small person, much less the 6’+ person who was next to me and had to put his legs over onto my side. Had a hard time getting my bag down between the seats to put under the seat in front of me. And everything was a cost, even water. Note to self, carry water or a drink on the plane if you think you will want one."

Cons: "We left late and arrived late. They ran out of one of the menu items."

Pros: "The crew on the plane were nice."
Cons: "British Airways misplaced our luggage for three days, and would give us no further information than "it will arrive soon." So, we were stuck near the local address we had provided in case they called for 2 full days. They refused to give us a more precise time as to when they would be delivered. Well, at one point they did say that they would be delivered at noon, but they weren't. Throughout the entire time waiting for the luggage to be delivered, there was no sense of urgency or concern on the part of British Airways. It seems missing luggage is just Business as Usual at British Airways."

Pros: "It all went smoothly and was on time"
