Nothing it was a nightmare

The rude security staff, my previous British air flight from Dublin was 30’minutes late. Heathrow is terrible for connecting flights even with 2 hour leg room. What a joke. English people suck.

Nothing I didn’t make the flight

Heathrow security is slower than molasses and rude. They had to check my bags and it took them over an hour. They were condescending and very unprofessional. Also extremely slow.

I love flying TAP because I love having extended layovers in Lisbon. Lisbon itself, including the airport, is easy to navigate. The food is great and the culture and architecture is gorgeous. For shorter trips TAP doesn't have as many amenities as other airlines, but on this trip the typical video screens with movies, music, etc. was available.

In this particular flight there was a male airline attendant who was fabulous and who could speak many languages, including German. I noticed the other airline attendants seemed to be giving him a really hard time and weren't friendly at all. In fact, I rang a bell to ask for attendant help at one point and no one came to help. I was just a seat back from the area where the helpful airline attendant was available. I think that overall TAP flight staff could be a bit more open to being friendly. However, on the ground in Lisbon I've found the staff to be amazingly helpful.

Crew members were very friendly, plane was clean, seats were comfortable, and flight was much quicker than what I thought it was going to be. Boarding was a tiny bit unorganized, but overall flight was great.

Boarding was a bit disorganized. I had brought my carry-on but the lady at the counter said I had to check it with baggage (which ended up getting delayed once we landed for an additional 15 minutes)

Flight on time, friendly crew.

Not so good meals. For a 9 long-haul flight only one meal provided, other was a cheap candy bar. Other carriers do offer breakfast. Traveled with child and did not allow priority boarding at LHR. Limited leg room, I assume this already a trend well known by travelers.

The food and entertainment was good. We got into the plane ver quickly and we were seated towards the front

I have been flying for a while but it is so difficult to find out what fare class you have. the website is not helpful with bag check in information. $90 is way too much to check in a bag especially for an international flight the line at Lisbon for passports is way too long

The crew was very nice, we boarded on time and landed a bit early which was nice. We recieved little snack packs that had a sandwich and a granola bar or fruit snacks and a juice.

The seats were not very comfortable to sleep on for 6 hours as they didn't recline back too much but that is to be expected in 2nd class seats.

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.
