All of my clothes were completely soaked and wet when I got to my destination. The airline was careless and left my bag on the runway during a rain storm. Very disappointing! On the connecting flight in Lisbon we were made to wait on a bus crammmed in for 20min and standing. Unacceptable Very poor experience and most of my belongings ruined!

It was disappointing to have to pay for soft drinks/ water. The sandwich I wanted was not available. Servig happened to late in the flight.

Not good. Long lines for checkin. Cramped seats. Would only give one tiny cup of water. Had to use people movers. Won’t fly TAP again

45 min late. Priority is not a priority as they put everyone in the same bus a than priority become last.

The check in process was terrible. Took a long time to check in because there is not enough agents. Once we got to gate, no announcement to board, all of a sudden people got up and board. The seats were EXTREMELY UNCOMFORTABLE. It was a 3 hours international flight, and we were served one tiny cup of water. 😩😩 The temperature was so hot inside rhe plane we thought we were sitting in an oven. Very difficult to find a flight attendant for assistance. They ran up and down aisle to serve first class but never really look up to seve the rest of the flight. I would never fly on this airline again. The experience was horrible.

What didnt i like? You had to pay for seats after the booking was paid for. If i knew that beforehand i would have booked with emirates for a few dollars more

Most important was the effciency - on-time take-offs and landings, no missed connections, baggage arrived correctly. Friendly & professional crew. Less important was food/drink. Pretty spartan, but we'll know next time and bring our own stuff.

Great airline, new, comfortable and quiet planes. Plenty of leg room and state of the art entertainment system. The big downside is the connection in Lisbon. The airport is small and a bus is needed from the plane to the terminal. Is a mess, takes a lot of time, nobody gives an explanation, boarding zones are not honored, etc.

I thought Miami's airport was very disorganized during the Boarding.

Very efficient boarding - other airlines could learn from them. Friendly, efficient crew. Red eye flight, so dinner meal was irrelevant. Breakfast could have been more substantial. Seats reasonably comfy.

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

Staff had been really impolite at the boarding area and for both ways charged high extra fees without a reason. For the check-in luggage which was measured 3.5 kg and was confirmed by the stuff to cost 40 € , 60 Euros had been purchased from our credit card. When confronted staff did call us both liars and claimed to never have announced anything. Flight back , when not wanting to press a backpack in a measuring metal instead of hand measuring , staff got angry that one did not follow her order, which was than escalated by the team. Although carrying a baby anyways staff did not offer any help in the unreasonable process and than charged again extra money. Cabine crew has been friendly but this experience LL lead to not booking easy jet at all in the future. Check in process in Edinburgh anyways chaotic,to the family check-in and disabled check-in everybody else was guided for check in process, so people just getting in between each other, not possible to monitor your own stuff.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

It got us their! Delays Delays delayed, flight got in well after specified time, rental car firms shut at 11pm!!!! So from £300 for car to £689.. thank you Ryanair....

The distance between seats was narrow. So my recommendation is to increase it

As on the tin a fair price for a fair flight ✈️👌✈️

Very good, everything went straight forward, boarding, during the flight, landing and all on time Well done

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

I got denied boarding bevause they said they "ran out of seats on a plane"

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Ryanair is the worst airline in Europe and easily one of the worst in the planet

We have a lot to say when BA cancelled our flight the last minute and put us on Air France’s already overbooked flight; and took no responsibility to ensure we are safe and met our travels. It’s day 2 and we have not reached our final destination yet. BA took no responsibility, but were happy to keep the money! If it were not for third party ground staff at Dallas BA we would have not gotten to India. BA has a lot to answer!

Very good flight. Delayed but no due to any fault of the airline. Food service is half a sandwich and crackers with a chocolate pot for a 5 hour flight so eat before boarding.

The lack of leg room for a 6 foot person makes for an extremely uncomfortable flight over the pond. Short little puddle jumper from Paris to London and back no big deal, but nine hours in a tiny and unbelievably hard seat makes me not want to do that ever again. This is my third trip to Normandy. FYI.

It was fine, seats were entirely too small. I’m not a huge man, and my hips barely fit in the seat.

In London, everyone was very helpful to make sure all passengers find the next aircraft, as everybody missed their connection due to the late departure in Miami. My mom‘s airplane left two hours after her arrival to London however, for my nephew they only had room on the next flight seven hours later. In the last minute they contacted him and was able to put him on the same flight as my mom./ which we were very thankful for Therefore, all his luggage was on the other aircraft and have not reached Budapest yet.

Quick boarding process, slight delays on the tarmac prior to takeoff and a late arrival due to an emergency on the landing runway. Not the fault of the airline at all! Cabin crew was very friendly and the Captain kept the passengers well informed about what was going on

Seats did not recline. That is none of the seats on the plane are designed to recline. If you want food you need to purchase it. We flew round trip Warsaw to London- both flights were late.

The port to insert the headphones was loose and had to hold it the entire time

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

During breakfast the fligh attendants missed one side of the plane for tea/coffee. I was on the other side and received tea. Unfortunately my husband and friends did not.

Were delayed in the airport for 5 hours with no explanation. Flight kept getting delayed by an hour at a time and wizz air staff were no where to be found

The flight was delayed 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.

It's a budget airline. Great for short flight. Smooth landing.

4 hr delay and only told less than 2hrs before. Only given water and nuts on the flight as complimentary service. Left to wait in rain before boarding.

To be honest I did not like anything. Communication to why my flight was cancelled mid air 2 and half hours into my flight. Customer service desk were not helpful with providing information or a solution on what can be done.

I have been treated unacceptably by WizzAir aircraft crew in a previous flight, they threatened me and abused me, and I received an OFFICIAL written apology, but only two (2) months later. This flight had no such unacceptable behaviour, but it's not nice to be left waiting in the walkway (from gate to aircraft) for a long time, just so that the 'boarding' appears to be early, even if actual departure is not.

What I liked new airplane Sitting was extremely uncomfortable! Crew not smiley at all Always chewing gum

The flight was cancelled just 4 hours before the take off...
