Flight takeoff was delayed an hour, but arrival time was not updated at the same time as departure time, so those picking me up at the other end were not alerted to the change in my arrival.

Flight takeoff was delayed an hour, but arrival time was not updated at the same time as departure time, so those picking me up at the other end were not alerted to the change in my arrival.

Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.

Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

Excellent flight and crew. Boarding at Dublin Airport was a very difficult trying to find the right gate.

I liked the front row seats. A lot of leg room. The check-in window needs to be longer

The actual flight experience was great. The handling of my luggage was terrible. First, I had to check in at the airport and wasn’t able to check in online because they booked me with a partner carrier in the U.S. that was incredibly inconvenient. I was also told that I would have to check in again with the partner airline in the U.S., also incredibly inconvenient at a large airport. Second, when I was at the counter, they did not tell me my carryon was too big. I only found that out when I tried to board the plane. I don’t know that it actually was too big though. It’s a standard sized carry on that I’ve never had issue with on any planes before. They assured me my bag would be checked all the way to my final destination. Due to flight from Paris to Dublin being delayed, I was rebooked on a different transatlantic flight to the U.S., which resulted in a different connecting flight to my final destination. My luggage was rerouted and I was assured it would be at my final destination. When I got to Newark, I received multiple phone calls alerting me that my bag was across the airport at a different terminal and that I needed to go pick it up near the baggage carousels. In the Newark airport, every terminal has its own security checkpoint. Leaving any terminal and entering another one requires a security check. At this point, I had to go through security in Paris, then again for US customs and pre-clearance at Dublin, then a third time when I had to change terminals at Newark for my connecting flight home. It was at this point I received the call that I needed to retrieve my bag from literally the opposite end of the airport and go through security A FOURTH TIME. These was no notification that I needed to do this before I went to the gate for my final flight. It took me an hour to go do all this, after I had already been traveling for 19 hours while sick and should have been home already were it not for the delay of my original flight. I retrieved the bag. My carryon became a carryon again and fit just fine on the last plane, by the way. I would also like to mention that my TSA flight information was not included on my ticket, so once again, I had to go to the airline counter to get my ticket corrected and reprinted before I could go through security and try to save myself time. Finally, I have celiac disease and prefer not to eat meat. There was literally no food I could eat on the seven and a half hour flight across the Atlantic. When the flight attendant woke me up for dinner (I would have preferred to sleep), I asked if there were any gluten free options. I was told the only option was chicken. I begrudgingly accepted because it was the only option, hoping anything else in the meal could be eaten. There was plain rice and a few green beans. The side dish was teriyaki vegetables containing gluten. There was a piece of bread, containing gluten. There was a custard, containing gluten. I could eat literally nothing except the very small amount of rice and green beans. When the same flight attendant came around again, while I was sleeping, a sandwich was placed in front of me, again food I could not eat. And this was after I got to the flight to find that my newly assigned seat on my transatlantic flight had been given to someone else! It’s like nobody communicates over there. This airline has the worst logistics of any airline I have ever been on, and I travel frequently. Dear Aer Lingus, DO BETTER.

Dublin airport is big and US Customs and Immigration screening officers are is part of the process there. This eliminates screening upon arrival to US, however should be taken into consideration when playing your transfer. After all, pleasant experience enhanced by draft Guinness and Irish coffee at the buffet area near the gate. We loved boarding by the row, back of the airplane first.

I like the price. I dislike the website where I wanted to ask questions about the unusual high prices of the luggage fees. I called the toll free number from the United States and I cannot get through. You should test your own toll free website for info and you will know what I am writing about.

Wonderful just hope the had more direct flights to Boston

Boarding process was fast and efficient. Short flight but on time and well organized. I would certainly fly TAP again.

Very borderline, low budget airline without low budget prices There are no counts of soda, everything is dispensed enlarged bottles and poured into tiny cups about 70 mL so in order to keep hydrated you have to take 3-4 cups at a time. Also, there was only one food item offered, pasta, they ran out of chicken right away. Snack was very poor. It was called tuna sandwich, which is truly borderline. The flight attend attendance seemed to be overworked and tired.

TAP‘s flight attendants seem to be among the least ambitious of all the international flight crews we’ve flown with. . When we left US and went to Portugal, and when we returned from Portugal, flight attendants were not very visible. Then did not offer frequent water breaks and when we had to go back to request water, I was almost an imposition. Meal quality was just average. The dinners were fine. Breakfast wraps were presented soggy.

Did not enjoy the meal provided. The aircraft was dirty. For instance, the screen seemed to have been cleaned with a dirty rag. Disgusting.

The business class seats were smaller and closer together than other airlines.

Boarding- Good Seat Comfort - OK Crew - Good Food - Mediocre On Time - Very Good

Didn't like much. Wheelchair assistance was almost nonexistent. No one at TAP check in process helpful. On the plane, stewards were not friendly and disorganized. Food was terrible for 8 hr flight. We were skipped at snack time and even though we tried to get attention using overhead call system no one even looked up at us to acknowledge. Being at the back of first section and by the lavatory we only were able to request when they came to pick up everyone else's garbage and they were nonchalant...no apology or even choice. The 1/2 half bread with slice of cheese was a waste. Deplaning was horrible but I'll blame lisbon airport for that. Plane left late at made good time still arrived about 15 behind schedule and for using remote deplaning and bus to terminal took another 20 min to gate. Those with connections were highly stressed. Took us 2 hrs from landing to get to ground transportation and exit airport. And that was with wheelchair assistance.

Bad boarding, threat to force bag check mid journey, lines, late, buses, more waiting awful end to end.
