Flights from London to Southeast Europe: the best tips from KAYAK users

Insights shared by verified travellers who flew the route from London to Southeast Europe 
LesleyFlew with Wizz Air-Feb 2026
Wizz air were great. We paid for fast track security which meant no queues & straight to duty free etc.
HamishFlew with easyJet-Aug 2024
Get there early to avoid queues at the airport
MarkFlew with Sky Express-May 2024
Don't forget your book, ipad or laptop to be able to kill those 3.5h hour flight.
NeelamFlew with British Airways-Dec 2023
British Airways and Bulgaria Air fly direct to Sofia from Heathrow. BA is better as hand baggage allowance is 23 kg. The downside is they give you no refreshments. Just a tiny bottle of water and a ridiculously small piece of snack with maybe 5 bites of nothing! They do however sell food onboard which is pretty overpriced and tastes lame so better to buy food before you board.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

It was appalling, full of young people who were drunk and disobeying instructions to sit down. Crew did nothing to enforce. There was a Ryanair pilot sitting in the aisle opposite me who talked through out the safety briefing so loudly I couldn’t hear. Whole thing felt unsafe

Delayed for 2 hours lack of communication no refreshments as promised and the drinks on board were not as ordered and refused to refund

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Blood contaminated tissue was stuffed to the back of the seat in front of us.

My flight was delayed 1 hour. My Mood was not great

This time round it was very good, flight delayed by 30mins but capitan put his toe to the floor and made some time up!!

Keep track of your departure times and communicate in Airport. I could have spend an hour more in my lounge

Flight was two hours delayed then instead of flying to Gatwick we got diverted to Southend airport! Then they cancelled our flight and we all got told we had to get off the plane and make our own way to wherever we had to go? EasyJet just abandoned us, no help and as a tourist not knowing even where I was? Disgusting behaviour from the company!!

There was no useful information given regarding the flight back to the UK from Tenerife. This despite the week publicised problems around the EES system and the delays caused to boarding. This aspect of the customer experience could have been much better.

Fast boarding, smooth takeoff and landing. plenty of space in seats. Excellent air-conditioning on a hot day. Perfect experience

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

The best budget airline in Europe. Flight was on time, crew friendly and worked hard during flight and were able to meet our needs. Only downside (not the airline's fault), there were no rear steps.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

Would not advise EasyJet for a 5 hour flight…small plane and hence a lot of turbulence. No inflight entertainment so struggle to pass time in cramped seats. We also fell victim to extra charge for our cabin bags, although bag dimensions were ok, but the handle was rigid and slightly fell outside their testing cage!!….never again will we fly with this airline and be party to their scams for making money!

The food and so are to expensive and old . Crew whas not very friendly . Apparently some other passenger can just Push through the waiting people to board while almost punching me and a father with a child down the stairs. Its always something with easy jet . The seats of row 26 where lose . And for a guy of my size there is absolutely no leg room at all .

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

Really slow transfer after getting off the plane at Manchester, and lost luggage! Take the train, terrible experience on arrival

Because kayak scammed me with false advertisement saying 23kg was included but I ended up having to pay another £200

The flight was canceled and I was directed to Air France two days later than my plan departure day. This involve getting two more days of hotel and also not being able to get a boarding pass until I got to the Istanbul Air France boarding desk. It has been a troubling time.

I didn’t take that flight. My original flight was cancelled from Los Angeles. They rebooked me following day through Montreal My flight was LAX to YUL and YUL GVA

It makes no sense for several types of drinks to already be out of stock in the middle of the flight.

Pleasant and friendly staff. Comfortable aircraft. Speedy boarding. Took off on time. Arrived earlier than scheduled. Overall very enjoyable flight.

I have a walker I need it to get from the plane to customs and baggage claim. It had a huge orange tag on it saying it should be given to me as I got off the plane. It was not and the flight staff didn’t know where it was—both on my flight to London and on the return. In It was very frustrating

They forced me to check my wheel bag because there was a full flight. This was very frustrating. I went out of my way when planning my trip to not have to check any bags. Usually, they ask people if they are willing to check a bag they do not force people. This felt like bad planning on the part of the airline.

Had a plane! Have a plan! Have my luggage! 10 hours of travel turned into 50 hours. Good Lord!

Those seats were very comfortable. Nice leg room and food was great 👍

Flight delayed but lack on information at the airport - only knew from looking at flight radar Other people queuing ages before a plane was there as staff not informing them of delays Usual issues with boarding people haphazard What is the point of priority when they don’t stick to it and all held like cattle just before getting on plane

The flight was on time, great value and very helpful crew. This direct flight was the most convenient I ever had coming to Sarajevo over the years. Will definitely use this flight again in the future without hesitation.

Very late to leave, poor communication on expected departure time and when boarding actually started.

Cheap flight but I didn't like the almost one hour delay because of paperwork!!!!

Gate is far at Leeds Bradford Airport. However, as the flight was less than half full, it was calm and not stressful. Great take off and landing. Friendly staff

Boarding was started early and we were lined up in. A glass tunnel on the tarmac we were left standing there for an hour with no information the flight left and arrived 30 mins late

It was great. We arrived a few minutes late but the crew were concert and kind about it. It was a nice smooth fly thanks be to Jesus. I prayed for smooth flight and Yahuwah answered my prayer.

We bought tickets for £30 from kayak but we paid £55 for check in to rayan , they slaught us

After you made us check-in I tried to add a suitcase in the internet and also to get help by chet. Nothing work and we pay 60 pounds at Airport. Comper to Easyjet to do the same, was easy and customer friendly.

I were there 20min before departure and they didn’t let me on the board with 5 other people, after all they admitted it was their(Ryanair) fault.

Far easier than I expected it to be. Checked in online & had our boarding passes emailed through. Straight through security & boarded on time. No issues.

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.

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 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.

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.

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...
