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

Economy is a little tight but the short flight isn’t bad just have headphone and 1-2 movies downloaded to watch
MatthewFlew with RyanairATH-STNFeb 2025
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.

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

Good but both flights were delayed by nearly one hour making boarding tedious. We had to wait with no information

Unnecessarily delayed and remarkably inefficient boarding contributed to a significantly delayed departure. Seats/legroom astonishingly uncomfortable even by Ryanair standards (minimal legroom plus reinforced plastic seat backs ensure you get punched hard in the knees every time the person in front moves, and as a 6-foot passenger I had nowhere else to put my legs. Upon late arrival at the gate in Luton we were kept waiting another 20 minutes before being allowed off the plane. Both Easyjet and Wizzair are currently a better bet.

This was the worst boarding ever. We were kept in the boarding bus for almost 40 minutes without any information or update. Very uncomfortable beings squished with another 50 people and not knowing what was happening.

Awful as usual the air stewardess loved her own voice and would not stop talking on coms for 2hrs please please please shut up I can’t hear my headphones and don’t want to buy juty free

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

On time boarding, on time departure and early arrival. As it should be. Yes, the comfort and benefits are very poor, but therefore the ticket is 6 times cheaper than with a flag carrier. So I am not complaining about it. You get what you pay for.

Boarding was fast and efficient. The crew was super friendly. Since it’s a budget airline and it’s a short flight, I can’t expect food or entertainment.

Good value for the money. Good leg room. Take off and landing very good.

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…

Boarding kept us waiting for ~15 minutes in the sleeve. Other than that, excellent for a low cost carrier.

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

2 hours delay, very disappointing, at least they didn’t cancel at all as they do often

I miss my flight due to boarding pass won’t load up

Flight schedule was modified and the final departure time delayed.

Big delay because of the weather but communication not so good. Boarding already late (due to tight schedule on Wizz side). When you get in you are hurried every second even if you still need a few seconds to arrange your bags. Food far away from how it looks in the catalogue and right on row 8 already out of chocolate although you are supposed to receive one for a menu. No replacement was offered.

The border control opens at 4:30 so there is no point in going in early as the wizz email suggests. Our flight utilized a plane with plastic seating which was really uncomfortable.

Check in took very long. All three priority agents left for lunch or something and the line did not move.

Il n’y a pas eu de vol du tout puisque celui à été déplacé à la veille sans aucune information. Aucun remboursement ni service client non plus. Scandale !

I planned to be working during the flight but next to and in front of me there was a family (basically all around me) who had screaming kids all the way long and they were rude and the kid was kicking me as well and constantly wanted to grab my phone etc. I was so pissed, I didn't think they will travel priority so I didn't think they'll sit next to me but they did. I asked the crew if there is a chance for me to go to another seat far away from there...And they were so kind, immediately after take off they showed a seat for me that is far away from these people. I'm so grateful for this!!! I hate that I cannot figure out these things in advance. I WOULD BE HAPPY TO PAY MORE IN ADVANCE TO MAKE SURE THERE ARE NO FAMILIES W KIDS AROUND ME!!!!

Brand new aircraft Airbus 321neo, good seats although no recline (so no arguments with other passengers). Orderly boarding using front and rear aircraft doors for efficiency. Departed on time and artived 25min early. During check in, ground staff are very strict about permitted baggage and carry-on weight and size - you're only allowed what you paid for. Onboard food and beverage prices are a bit high but similar to airport coffee shops.

Boarding was fine, crew professional but not very friendly. Seats are very tight & uncomfortable. 1h delay due to crew change and mechanical issues - no communication whats going on.

Crews are great, chill, good snack sets on offer, I didn't feel they play any annoying budget airline games. I will probably fly with Wizz every chance I get it

If you don't want to pay a lot at check in desk, you need to use online check in tool, but you still need to go to check in desk to have it printed out. Then what's the meaning of "online check in"? Extra security check, as if 9/11 just happened!

After adding baggage costs, and considering the necessity to re-checkin at each stop, and the €50 I was tricked out of for the ridiculous 3 hour min check in, I’ll never fly this very hungry Hungarian airline again!

This airline is routinely voted the worse airline in Europe for good reason. If you have an option, just avoid them.

Everything was great until it came time to pick up our luggage. We arrived in orly airport terminal 1, our luggage arrived in terminal 2. No signs to tell us, we waited for almost an hour before someone figured it out.

All in all is not bad, but the boarding by walking outside in the airport airplanes area in the wind and rain to go up the stairs to board the plane that’s too much inconvenient. Hopefully that will change and we use the normal gates at the airport to board the plane! Thank you!

The plane was 5 1/2 hours late. Scheduled for 19.50 take off - Actual take off 01.30am

The payment system was not working so was unable to connect wifi the entire flight

I didn’t have food and they don’t include entertainment. Not much leg room at all. Staff were great.

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

When Stephen arrived with our wheel chairs - we were in excellent hands! He was such great help with getting our rental car and then reporting our missing luggage. When you are exhausted from traveling for too many hours, he was just what we needed to navigate everything! Give that guy a raise!

Full flight, but crew was great. No wifi and no seatback entertainment, so had to read...argh!

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,

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!

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.
