Be sure to have at least 2 hour layover when flying through London. Also, we have TSA Global and when we checked our luggage, asked to confirm it was on our flight. We were told it was. It was not

Bring food, drink, entertainment and prepare to remove clothes as temperature was super hot and air system barely works.

If you’re flying abroad from Zagreb, it’s worth using the airport lounge for a few hours before the flight. Food, snacks, drinks, and a quiet place to unwind. For less than 20 quid per person.

Watch out for transit times in Heathrow. Always put your liquids in the little stupid baggies.

Got what we paid for. Food option. Need to carry more stock.

Usual slick event. All the basics covered well. On time, plane full.

The staff were lovely but the plane was very cold .

The flight departured two hours and a half later than the original time flight. We loose our bus and it cost us 108 £. We are not repeating

Has always great flight. You get what you pay for.

3 hours delay, little communication, no refreshments provided despite legal requirements

On time! The wait to board standing outside was miserable. The “priority” boarding is misleading as it does not help the boarding process at all. The bag charges were very high and my expected carry on did not quite fit in the measurement box. The lobby experience at the airport was terrible! Signage and directions were inadequate. The staff was all lovely.

Late boarding as our plane was late arriving from previous flight, then 3 hours sat on the tarmac waiting for a time slot. Then, when we arrive at Birmingham airport, we had to lug our bags down the plane steps, cross the tarmac and lug our bags up the stairs to enter the airport. Horrendous!

Sadly the experience with the airline is worse one ever. Starting from the state of the inside that was filthy that flies was flying around our legs. The food is expensive than a restaurant, imagine a family of 4 spending almost £50 for just sandwich of bread and ham no tomatoes and lettuce in it and a small container of crips that is not up to 20 pieces and a can of coke or Pepsi, and unfortunately that is a person ffour hours pay of work before tax. I know the blame will go to high cost of living but even at that the price is too much.

Easyjet staff very helpful at airport as I need assistance. Flight slightly delayed both ways but soon made up the difference.

Flight on time clean and good legroom, what more could you ask on a one hour flight

There was a delay because they had to switch planes it wasn’t explained very well nor were there updates.

Flight was cancelled. Then left virtually completely in the lurch

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.

It was good except they could offer free water and tea/coffe

Sat at rear of aircraft and was very cold. As a frequent flyer for many years, this is was the coldest I have ever been. Other passengers and some crew were complaining how cold it was. Sitting near the doors always risks being colder, just the way the aircraft works - but this was exceptional, bring a good jumper. Everything else was pretty standard easyJet - good value low cost carrier.

2hrs delay on both ways Captain has to change his mind on landing in Birmingham airport and being forced to escalate and fly again, bit scary

Very poor No respect to people Only motivation is to charge extra money from travelers Never again

Payd for long seats for our parents and because they don’t speak English fluent they have moved them. Absolutely scam!

The chairs don't recline and the food for sale didn't looks as appetising as its prices would suggest. But that's a low coster for you. Orher than that, the flight was delightfully uneventful.

The flight never took off because two naughty kids, Donnie and Bibi, did a silly thing. Started a war.

Even when you get the priority pass the experience is not what it meant to be priority

Low cost carrier, you get what you pay for. Cardboard-quality seat, no recline, minimum pitch, bus-to-board service (no jetbridge), and overworked/underpaid flight attendants. But, they got the job done on-time with no major catastrophes.

The behavior of the front desk and lack of explanation of hidden fees and prices in emails send pre-flight marred things up. 1 star

Flight schedule was modified and the final departure time delayed.

Communication was impossible: feedback was missing, no alternative communication options are offered. Check-in without feedback and the status was unclear at the airport until the last minute. A whole weekend under full stress. Never fly again but never use your platform again!!!

Disappointed as we discovered when checking in at the airport 6hrs before the flight was scheduled, that we had been offloaded onto standby after having purchased these tickets months in advance. We had tried checking in online the night before but were unable to. BA had obviously over sold the seats, and we were told they couldn't confirm we could get on the flight until check in closed. Eventually we did get on but were not seated together. That was a bit of stress we just didn't need.

My flight from Athens to London was delayed 30 minutes. I got automatically booked on a different flight before the plane landed. However, I never received any notification about the new booking so I had zero knowledge about the flight number or even where to go. Checking in: it was absolutely impossible to check in for my flight online. I literally had to call British Airways to check in for my flight and select a seat. It was very inconvenient and a bit stressful.

I ordered a drink, but never got it. I ask what type of drinks they had and they could not tell me and there was not printed copy that I could find that is usually on most airplanes. They served dinner and never walk back to see if any need a drink or anything afterwards until they served the snack just before landing.

Check-in wait time was quite long (understaffed for the volume of customers), but energy and hospitality of flight crew was great!

I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

Flight held at gate for other passengers. We ended up being late and missed connection

Should have more cosmopolitan food choices - too many Indian dishes - the only entree not Indian was lamb which I don't eat

The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.

Worst thing: Luggage took forever to get at LAX despite priority bags. Best: Flight attendants were great!

The cabin crew were working extremely hard making passengers calm down and take their seats (it looks like this is a problem of flights to/from Tel-Aviv) and they were visibly tired. So, the crew is the best, but all the other Wizz Air pros and cons apply – reasonably priced tickets, narrow seat intervals, non-reclining and somewhat hard seats, messy boarding because of little overhead locker space caused by narrow seat intervals. Both my flights went on time, which was great.

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.
