Flights to Oeiras: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew to Oeiras 
Verified travelerFlew with TAP AIR PORTUGAL-Apr 2026
I have greatly enjoyed Tao Portugal. Nice service. Just be aware they weigh both your carry on and your personal item at the same time at the airport counter when you check in for the flight. Both can not excede 12 Kilograms.
ShilpaFlew with TAP AIR PORTUGAL-Dec 2025
Seats were comfortable- vegetarian meal was pretty mehhh- maybe pack your own meal
FlorenceFlew with TAP AIR PORTUGAL-Dec 2024
Both flights needed a bus from terminal to plane and plane to terminal. The transfer to the connecting flight at Lisbon was quick and easy with luggage checked thru to Venice.
Jose AntonioFlew with TAP AIR PORTUGAL-Dec 2024
If you have connections make sure they are at least tree hours from your landing time
Verified travelerFlew with British Airways-Sep 2024
Make sure you arrive early enough for boarding. I had a 1 hr layover from Charleston that that was just enough time to get off the plane and walk over to the international side before they started boarding.
LexFlew with TAP AIR PORTUGAL-Aug 2024
I had long wait at customs. Please plan accordingly.
ThuFlew with TAP AIR PORTUGAL-Apr 2024
Weigh bags. They will check. Check in with gate or desk. Sometimes the e ticket will not work for boarding.
MaximFlew with TAP AIR PORTUGAL-Mar 2024
I was waiting for a flight boarding announcement in the Lounge in terminal C at Logan Airport in Boston, but the announcement never came. If I did not go to the gate to check, I might have missed the flight. So, do not count on the airline to communicate flight boarding information to the lounge staff. They are supposed to do that, but, apparently, sometimes it does not happen.

Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delta exceeded my expectations! I am beyond satisfied. Thank you!

Flight was on time! That's the most important thing for me.

Delayed flight. Dirty seats, dirty seat belts with food stuck on it from previous passengers maybe. No one cleaned the seats or flight.

The flight was delayed and knowing I was going to miss my connection, nothing was done proactively to try and get me rebooked. It was an act of congress to do so. This is not on the crew, but on the experience itself

No headphones, forced to sit in another seat that I did not book, had to check my carry on when I boarded the plane I saw backpacks and other non carry on items stuffed in the carry on holder! Horrible experience Wi-Fi did not work either

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

All was fine. Small plane so no food or entertainment.

Overall Delta was amazing from automatically booking us on the next flight once we missed our connection due to a delay to the constant communication throughout the entire process. We will continue to fly Delta going forward more and pay a little more if needed.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

WiFi was slow as compared to trip down. Maybe because it was a night flight and more people were using it?

Excellent except for the 2 screaming kids who wouldn’t stop crying and screaming for the entire flight but what are you going to do? The flight was early- good experience

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

It was partially ok .. not anything like from Orlando to Houston... first the flight attendant was not so nice and insisted on have a small backpack down when really was not to put in danger anyone, also the beverages they were not so good... not big chance to select other tea.. the seat was partially ok could not have those flips to hold your head.. and finally when it land off in Guadalajara, it was raining and the flight was going to the main area then go back and drop us out of nowhere with the rain.

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

Excellent experience - from boarding through the super smooth flight The food was mediocre and the app could be better but overall great experience

This was one of the worst flights I have ever taken in my entire life. First of all, I traveled Economy, but the seats were TINY and cramped. Not just for me; everyone around me was complaining of the same thing and said they could not get comfortable. Then there was the issue of the heat. For whatever reason the heat on the plane must have been turned to FULL BLAST, because even at 30,000 feet, it was SWEALTERING. Everyone was drench in sweat. Then, they were SO STINGY with the amount of drink they would give you. If you asked for water, it was in a tiny, paper cup (think bathroom cup) and they only filled it 3/4s of the way as if the cost came right out of the pockets of the air stewards. Everything was a money grab, you could tell! You had to pay for the WiFi, which was garbage slow, and the onboard entertainment was limited and stale. If I EVER fly TAP again, it will not be Economy class. What a disaster!

They blocked me from checking in online and they charged me lots of money

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

Not have my bag forced to be checked when I had a carry on included on my ticket. Staff was very rude to me for asking why they were doing this. I was told there was no more room for carry ons but there was plenty of space in the overhead compartments

The crew was excellent. What I did not enjoy was the food. I have taken many international flights and this was on the low end. Otherwise the trip was fine.

Seats were the most uncomfortable seats i ever experienced on a flight to Europe from Boston. It was a waist of money in buying premium seats for top dollars. I want my money back for what i paid extra for my seats. Awful conditions!

Boarding felt a little chaotic as everyone was waiting around the gate. Food was great, service was good.

Flight attendants in business class were rather indifferent While in second leg operated by Portugalia TAP subsidiary were outstanfy

The chicken was so dry it was impossible to eat. No substitute was offered. The port to charge my phone was broken and all I got was a shrug from the crew. The entertainment system was glitchy and subtitles didn’t load. Crew seemed fully uninterested and unfriendly.

My flights were all delayed , mostly due to technical issues with AA aircrafts. I had to rebook my trip 4 times . I lost my whole day and finally arrived in LAX around midnight. This was a very bad experience with American airlines , I will always try to avoid flying with them

AA was fine....the overall experience was subpar, but not due to the airline due to broader issues

Delayed and WIFI was not working for most of flight.

The big challenge here was that the inbound flight was delayed, THEN, the aircraft was deemed in need of service, so we had to deplane after being a few minutes away from departure, THEN we had to switch terminals, where another plane in our gate had maintenance issues so we had to change gates again. I am a regular flyer (not on American) so I understand these things happen. The crew was great. The pilot in particular was gracious and understanding and stayed with the passengers the whole time to answer questions and give updates - that was impressive. But the flight was massively delayed as a result, and today I really wanted to be home in time. Sigh The flight was otherwise great.

I am Plstinum Pro snd was standby on earlier flight. They gave seats to people that asked rather than follow standby order. When realized what was happening was too late to get on as no seats left. My scheduled flight was late. Then filled the seat beside me Ruth rude person that they had to move from her original seat

My flight was delayed close to 10 times over the course of the evening. I was originally scheduled to depart at 7:03 PM but did not leave until 12:33 AM, resulting in over 9 hours spent waiting at the airport. The only explanation provided was that the aircraft kept being swapped, with no clear reasoning as to why. Weather conditions at both DCA and Tampa were clear, so that was not a factor. The only accommodation offered was a $12 food voucher, which was entirely insufficient given the length of the delay. Overall, I was completely unsatisfied with this experience. A delay of this magnitude with no meaningful communication or accommodations is unacceptable, and I would have expected much more from American Airlines in terms of customer care.

No ground air conditioner for the plane. Very hot and humid prior to take off which was an uncomfortable period of time.

Check-in process was poor, very poor, only one person to check-in all passengers, so if one passenger had a check-in issue, all other passengers were delayed. All check-ins should have two airline staff to check-in passengers.

Flight was cancelled due to a myriad of operational issues. You guys really suck

Bathroom ran out of TP and floor was wet. Crew seemed a bit unhappy, overnight flights may be harder.

My bags were lost. I waited in a line for 5 hours after I landed and got no resolution to the issue.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

The on flight entertainment system touch screen system and the USB charger did not work on multiple seats on least 4 seats an in different rows. The attendant tried to reset the system but was un successful. I couldn't change my phone to get my ticket for my next flight. This was an international flight I changed seats and the problem was the same. the flight attendant offered his power bank

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

Once again I purchase a business class ticket and the seat is exactly the same as cattle class, the only difference being is that BA install a janky table over the middle seat so there is somewhere to place your complimentary drink, the tray table is just big enough for the small tray, so if you are not concerned about getting fed and watered on the plane or getting access to the BA lounge I would save your money and fly cattle, PS the cabin crew were exceptional in every way, shame about the equipment

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

A Perfect 2.5 hr flight. No amenities, but we did not expect any.

Delayed flight by 45 minutes. Need a refund to compensate for the subsequent itinerary changes

The flight was delayed and absolutely packed, we had to dispach our hand luggage which contained some fragile items, luckly nothing was damaged.
