The food is pretty low quality, but I understand the logistics constraints of feeding many people in a small space without kitchen facilities! Also the wine choices are superior to other airlines and I look forward to that. I normally plan ahead and bring my own meals whenever traveling by air.

Did not take the flight in the end

My first leg flight was delayed and I booked through kayak on two different airlines and the first airline did not communicate with the second airline so 5 passengers ran to make the change and arrived 1 min after the jetbridge to get on the plane was pulled away. It was incredible frustrating and could have very easily been avoided with communication from the airlines

Having had bad experiences with Aer Lingus before, I was hesitant to book with Aer Lingus again. But sadly, I was booking this flight last minute and had no other option. The route was Dublin to Calgary, via Toronto. I left myself plenty of time im Toronto to clear customs as I know it can take a while. The day of, the flight ended up being 1.5 hours longer than usual due to headwinds, leaving me with only 2.5 hours in Toronto. I ended up waiting 2 hours and 15 minutes for my bag and missing my connecting flight (my sister who was also on the same flight received hers in 30 mins and made the flight). Westjet was wonderful and put me on a later flight but Aer Lingus didn't have any assistance for me.

Aer Lingus lost my sister's luggage going to Ireland and never contacted my sister once the luggage was found. She only received it the day we flew back to Calgary. Poor customer service when inquiring about the bag, no compensation for necessities purchased.

They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

The movie selections and comfortable headsets made it possible to watch three movies uninterrupted. The food selections were well prepared. Flight attendants were helpful and efficient.

Boarding is always a bit of chaos when our seats are right in the back. People further up insist on boarding early and block the aisles in the process. Multiple levels of passport control and baggage checkout are chaotic, but that's for most all flights coming into USA? VIrgin/Delta handled it well enough. By the time we got through passport control in Boston ur bags were waiting and we had no problems at all.

The whole flight was great quick boarding, lots of leg room, good entertainment, a USB charge port, good lighting, and the crew was very nice and helpful. I enjoyed the flight and would like to fly Virgin Atlantic more. Finally, you are the 3rd best flight, I have ever take, and the 2nd best airline I've been on. Flew Business Class on Swiss Air once to Geneva (#1) and all the flights I have had with Porter Air are comparable to your airline, but the free cookies and beverages at Porter's terminal in Toronto wonderful.

A couple things went wrong on this trip, my checked luggage got misplaced for a day, and a nice women in baggage claim told me what was happening and a nice man handled my claim and my bag has now been returned to me. The bigger thing is my flight bas delayed taking off by 3 hours. Let me start that I would rather have a part replaced on the runway then not, safety is paramount. The fact is my flight took off 3 hours late from London (VS11), and got to my destination (BOS) 2.5 hours late. Kudos to the flight crew for getting me to my destination faster by gaining a little time. Plus, since BOSTON was my final destination it was all fine this time. But if I had had to get home to the elder person I take care of or my teenager it would been a problem. Again, I'm annoyed, but I do understand the reasons and they are valid and preferred. I have heard that airlines to keep their flight rating high, wait for planes to leave the gate on time and then do repairs on the tarmac. If this is still a SOP for airlines you should change the way the statistics are collected and figure out a way of not perpetuating this type of disincentive. This is just hypothesis on my part, and my whole trip had little negatives.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals 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.
