Reviews of the top 4 airlines serving from Portugal to San Francisco

Delta is always late. Ruined our first day of a short vacation. Timing is important. We pay to stay on an itinerary
We sat on the runway for over an hour before departure. That was unwelcome.
Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.
One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop
WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.
Generally on time departures and arrivals, clean planes, sky miles membership provides great benefits (complimentary upgrades, etc).
my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful
Awful - both legs. The check in was awful, getting on the plane required walking down a spiral staircase (dangerous), then taking a bus about 5 miles out from the terminal. The seat was broken (I was in business), there was no internet during the flight (both legs). The aircraft was very old. I saw rust in some place, tape holding things up in the bathroom. This was an unacceptable experience for such a long haul flight.
I usually get upgraded so my experience is usually amazing. I did not get upgraded this time - which was fine - but the wifi had issues, the monitors were going in & out, & (though not Delta's fault) one of the gentlemen next to me desperately needed a shower.
First class flight crew was barely available. They came through 3 times while we were on the plane for nearly 4 hours.
United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus
Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.
For the Singapore to CA flight, nearly 16 hours long was miserable. We sat on the tarmac for one hour to burn fuel. The flight attendant girls were mean. They would yell at people who stood up to try to stretch their legs. One time the drinks came thru and the lady judged us and made a comment about how much sugar was in apple juice when we ordered it once. She was rude and inappropriate. The entire flight was frustrating. You'd think a long haul like that the airline would try to make you comfortable. I just don't understand why the ladies were so snappy. I have never experienced rude flight attendants like that. It was the longest flight I've had to sit on before. We were not impressed. Raymond on the other hand was amazing! By far the best person working that flight!
premium economy is expensive but worth it for the comfort and food on a long flight
Even though the incoming flight was delayed by 20 minutes they managed to get us to SFO 15 minutes early.
Boarding, time to take off, in flight offerings, and staff were all great. I recommend using UA for this short flight.
Good experience. Staff was friendly and helpful. Flight was slightly delayed due to airport construction, but they still arrived on time.
This is the worst airline I’ve ever been on in my life and I’ve been probably on 75% of them. I said 15 years ago I would never go on United again. I was an idiot. I booked a flight with them from Las Vegas to San Francisco and of course they screwed that up and cost me a day flying all over the world trying to get to Thailand. My luggage was gone for 35 hours all because they couldn’t make their route on time
The flight out of Fresno boarded 1.5 hour past scheduled and made me miss my connecting flight from SFO to SEA.
Excellent! Flight left a bit late but overall a pleasant experience.
Business class seats aren't comfortable. Food was not good.
The layover was only one hour and a huge line for passport control. If I didn’t cut the line and argue was every single official, I would’ve spent the night in this one. Obviously.TAP AIR people. do not take into account.this problem with their flight scheduling, which is extremely frustrating. Poor food choices, on the pasta was offered, they ran out of chicken right away. All the sodas and water poured in a tiny 70 mL cups, which is not enough to keep hydrated on the long flight. I had to ask for 34 cups at a time. Flight attendant seemed to be tired and overworked.
Got in on time. Food was the worst ever. Comfort was terrible. Check in was incredibly bad.
Flight delays. Mad rush with no help from staff. Staff for TAP is elusive like the Tasmanian devil... you hear about it but never seen it. Seats were the only thing that was ok as its lie flat, but trying to sleep was like being at a concert as the crew were chit chatting non stop while you are trying to sleep. Food was seriously better in Premium EY on other airlines like Singapore Airlines, Lufthansa, United. We traveled Business Class on TAP. Crew were friendly enough but not very present at lull period of flight.
Crew woke me up to see if I wanted food - NEVER want food on a 12 hour flight more than I want to sleep. Sleep was not easy, as a child screamed and threw fits 70%of the flight. That same child kicked my seat most of the flight. BUT, despite the child and a poor boarding effort, the rest was solid. The crew worked hard otherwise - just don’t wake me up IF I actually get to sleep.
Way too much money for the experience, would have been better in economy
It was excellent - good value; good service. No complaints; my sister moved to Portugal so I will be flying there annually and will continue to use TAP. I love that I can get nonstop flight from SFO to Lisbon.
If you miss any flight in a Multi-City flight plan with TAP, all remaining flights will be automatically terminated immediately. Their support line is no help at all, and you'll be stuck paying again for another flight.
the cancellation of my earlier flight caused me to miss this connection as well.
Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.
Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays
The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.
There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.
Audi visual not working for a whole group of seats in first class. How does a plane leave the main hub in such poor condition? How much that we can’t see so immediately is also compromised?
main meals are horrible but then you dont fly for the food
Great flight. One unique individual assisting in business class who should have not been there. Need more generic meals, not British centric.
It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.
I am a 25+ years American Airlines member. British Airways is simply above and beyond in every customer satisfaction category.
The crew were good. The flight was on time. The entertainment choice was ok. But the food was bad, tasted and texture were awful.
