easyJet is pretty good for low cost carrier. Because of the way the terminal is structured, there is a much longer walk and more stairs than would be expected. My favourite airport is LHR, and I prefer LGW over LTN, but LTN is closer to home.

Try the business class option as not much more expensive. You get three seats for two people, good food, drinks and more leg room plus priority boarding.

Cheapest transfer from Faro to Tavira was with http://airportstaxitransfers.com/ only €35.00 each way. Efficient and on time with great drivers and vehicles. Couldn’t fault them especially for a 4am pick-up in Tavira !!!

Web site needs improvement Plane was clean and modern Lay Flat beds were hard and not to comfortable (business class )

Let’s be honest. You know you are boarding a flight where the seats don’t recline and you need to pay double the price for bread, gin and water. But beware, they test your tolerance to torture pre boarding. They call all British passport holders. Then tag cabin luggage to be checked. And the ground staff pretend not to know what is happening and just says - please ask the other staff.

It poured rain, our luggage was sitting out in it uncovered on the transport cart while our plane was delayed! Nice business class plane for short flight to Lisbon, but more delay & rain in Lisbon, with terrible Business class seat with no entertainment & cold food on longer flight to London…ALL LUGGAGE AND CLOTHES INSIDE THEM WERE SOAKED THROUGH!!! Could only try with hair dryer to get some drying before quick turn round to train trip.

Menzies group staff not very sympathetic good at breaking up families during the boarding process

There was no warning that they have added passport control after check in, the line was enormous and after 46 mins wait we missed our flight. Were forced to leave the airport and purchase new tickets at full price to board a later flight. TAP were unsympathetic and unhelpful.

Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.

Not much to like. Check-in and bag drop procedures are a crowded, disorganized and confusing mess. Agents were grumpy and unhelpful, somehow expecting passengers to automatically know and understand the airline's procedures. Boarding was chaotic and included a stand-up, sardine-packed bus ride to a stairway pushed up to the aircraft out on the tarmac. Passengers were left waiting in the bus for a lengthy period on both ends. Flight departure and arrival were delayed by passengers scrambling to find space for bags in the overhead storage. Many passengers not in compliance with carry-on rules. Everything you could hate about flying in this ride.

Its a short flight with no entertainment. The food was so so.

Dreadful - queued to get onto a bus, stood for 10 minutes on the bus, drove to the plane, stood for another 25 minutes on the bus outside the plane. When allowed on we could only board from the front & were seated in the furthest row back. The second bus was allowed to board from the back so chaos ensued!. The flight was an hour late - nobody said why, nobody apologised. On arrival at Heathrow we stood for nearly 30 minutes before being allowed off - again with no explanation,

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

Ground staff a baggage drop in Palma were generally unhelpful. The flight was delayed and the boards were never updated and there was no communication on the length of the delay.

Over 2 hours delay, communicated last minute - and no acknowledgement by flight crew

Boarding was terrible. We were all cooped up in a small, claustrophobic space awaiting to be let out to walk to the plane. Very cramped and very uncomfortable.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Dislike standing for 30 minutes waiting to board. Coffee disgusting, hot sandwich almost inedible. Staff cheerful. Flight early.

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Seats are very small, I’m not a big person, but the person beside me was using his seat and half of mine… and this person was a bit gross but not a lot…

Cardiff is a great airport but they pen you in at a gate way too small for passenger numbers. Called to the gate too soon and air conditioning was not in operation despite the heat. Cardiff should do better as a small relatively quiet regional airport.

Good flight. Take off a little late but make up the time

I didn't like. The seats and the floor were very dirty and it is not the first time

The workers checking passengers from the boarding gate stole money from people whose luggage was perfectly fitting inside the carry-on sizer.

Whole way through - far more professional and slick than I expected

Good news was that Bag Check was open two and a half hours before the flight, which is essential with the chaotic immigration process. Flight was okay, but sitting at the back of the aircraft, 3 overhead bins on both sides were filled with crew bags and other misc items, so we couldn't put our cabin bags anywhere near us. To add insult, twice the crew managed to drop items that they were taking out of the overhead bins onto my wife's head, who was sitting in an aisle seat.

You need to make signage at Berlin Airport clearer. Having checked in online we had our boarding passes onlour phones. You do not make it clear that you need to check in again to receive a printed luggage tag. You get to baggage drop off and it says you can only do it with a luggage tag BUT not how to get this.

The true is that travel from London to Faro on 11/12/2025 by BA was cancelled, so I did not go to Faro, so i did not board easy flight. The mediocre qualification to you was because even when i bought an insurance, i could not change date neither obtain reimbursement. It could be ideal if you do something in order for me not to lose the purchase Thank you

Liked. The check-in was pretty quick as they had 5 desks working.

Well Is extra charge for everything and other companies include that and the price.

Comfort isn’t a word one uses on economy airlines! Boarding was okay, delayed but okay, the flight was good, quick and time was made up.

With stairs on a rainy tarmac, EasyJet flights are ok for younger travelers with backpack only. Seniors with mobility issues find it challenging 😰. However, the crew and disability assistance folks at both ends eased that discomfort as much as possible for their various roles. Kudos to airport and EasyJet employees for their kind service.

The flight boarded a little late but made up the time in flight - much appreciated. The staff were efficient and fairly friendly One of the toilets wasn’t working - having only one functioning toilet for a flight of hundreds isn’t really acceptable. I still find it amazing that the budget airlines can’t even offer free tap water to passengers.

First time flying with them! Loved it! Specially the schedule from Miami and being able to come back directly to New Orleans :)

The boarding was a mess as there was another document check in the small congested area after the stairs at the gate. No food is offered for Economy travelers except for a cookie and a small water bottle. No entertainment is available since it’s a short flight. But at least the seat reclined as opposed to my flight to Faro.

The transit at Heathrow was an absolute and total nightmare. Absolutely gut wrenchingly horrible and scary. Embarrassing that their National air carrier cannot figure a half decent experience for passengers to transit via London. Shameful.

I do not understand how BA takes coach seating and has people paying for business class. There is no leg room, seats don’t recline and no entertainment to be had unless you brought your own.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.

The flight was fine but they made me pay for my carryon bag because they said it was too big at the counter. But it fit under the seat just fine.

Outdated from start to finish. Good was inedible, choice was very poor. They don’t seem to care

I never got the flight. Someone hacked your information and sold me a fake flight. Didn't know this till I tried to check in and was told the flight didn't exsist and it was a fraudulent ticket. I'm not sure how to get this fixed but I had to pay $1500 to book a last minute flight. I understand that this was not Kayak company that sold me a fake flight but I was sold a fake flight based on my booking with Kayak. I ended up having to pay for an extra night hotel stay. I guess I need to start by contacting someone at kayak to get this resolved. My bank has stopped all bank transactions because of it.

Every flight was delayed. They lost our luggage for days.

As seats on planes seem to get smaller over time and people’s bodies get bigger significant mismatches occur. I was seated in the middle of a four seat center row on a 9 hour 10 minute flight from Heathrow to Seattle. The woman seated next to me was such a size that she required a seat belt extension in order for her to fasten the seatbelt around her. She occupied fully 1/3 or more of both my seat and my table. Her and her stuff also occupied most of the space for my feet. Not an enjoyable way to spend on a 9 hour flight. My most miserable flying experience ever.

Shocking. Faults with the plane in both directions which caused delays with no compensation

Very efficient boarding. Plane lready for take ooff10 minutes before time.

Great crew. Seats do not recline :( but it is budget so i should have known. Otherwise comfy leather chair. Slight slim chair but again budget so expected. No entertainment do makes journey boring. Recommend packing plenty of snacks and games or download plenty of films and music in your device. Staff excellent. Clean flight. On time.

Both of my flights had issues with their time slot with air traffic control, so they left over an hour late and the flight back to London was delayed by over an hour. Please provide more clarity about baggage requirements on booking sites, your website and within the app. I had to pay for extra bags at the airport when departing London, because they didn’t specify that your carry on bag can only be a backpack and not a trolley, my trolley bag fit the size requirements of the backpack but still I was made to pay

The crew at Check-in was very helpful. It’s was appreciate.

It’s a budget airline. You get what you pay for. They insisted on getting us out of the gate and into our slot on time. They got us to the destination safely. Aircraft was clean and well maintained. What more could we want

Half an hour delay. Squeezed into a small Departure Lounge with very few seats. Noisy flight with screaming unruly kids. Loud IPads and Phones. Heaven!

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.
