Proximity of the the gate to the lounge could have been better but overall a nice experience. The lounge was exceptional. Getting from the Schengen side to the international side was also pain free. Boarding the plane, service on board , disembarking at Heathrow and quick delivery of bags all made for a good overall experience.

Proximity of the the gate to the lounge could have been better but overall a nice experience. The lounge was exceptional. Getting from the Schengen side to the international side was also pain free. Boarding the plane, service on board , disembarking at Heathrow and quick delivery of bags all made for a good overall experience.

Again another extremely chaotic boarding for the flight. Could have easily opened up more automated gates and the staff could have proactively managed the queues as they're forming rather than sitting behind the counter, waiting for the boarding to start.

My flight to Frankfurt was a very pleasant experience. The food was good, but what really stood out was the cabin crew, who were exceptionally friendly, attentive, and professional. The service was excellent—honestly, better than on some much more expensive flights I’ve taken. A wonderful experience overall!

The flight from FRA to SFO was uncomfortable. The crew allowed people to change seats after boarding finished, but then made some people move back to their seats but not others, which resulted in my wife and I having to sit in two middle seats for an 11 hour flight. The entertainment system was not working well throughout the flight, and stopped working completely around hour 8.

Review what was entered already in the same booking. Not sure we will use Arrant Grant, given what happened!

Great service food was very good and overall experience was great !!

When I fl with Bulgarian air, I am greeted with a bottle of water and a packaged cleaning wipe. There is a hot sandwich and a drink offered afterwards. Towards the end of the flight, there is a piece of chocolate and per request an additional water bottle. For the price that Lufthansa charges per ticket, it is embarassing that other airlines can offer better customer service quality on board. Also, some of the Lufthansa flight attendants act very entitled instead of being customer focused. Regularly the mobile lift for diabled passengers is missing... Every time when I fly with my 89 year old mother, she is being questioned multiple times whether it is okay to use the stairs ( she walks with two canes). Most of the times when we arrive in Frankfurt, the mobile lift is missing and she is urged to use the staircase. When I refuse to allow this, the flightattendants look at me scornfully. This is not WW2 where disabled people should be treated as second hand people... Then we all have to wait another 30 to 40 minutes on the airplane, while waiting for the mobile lift to arrrive. Does Lufthansa have enough money to waste on an airplane waiting for (on the average) 30 min for the mobile lift to come? I fly frequently and have experience mostly with Delta, United, Southwest and other American Airlines. Lufthansa needs to pick up their game on board, if they want to stay competitive and in the game...

The Linate Milano flight was delayed. Landed at Frankfort at 12:10. Then took the bus on the tarmac and the bus ride was about 20 minutes due to the airport traffic. Got off bus went to passport control, used the kiosk scanned passport, took photo and finger prints and proceeded to wait in line. I asked the attendant that I had a connecting flight at 12:50 his respond was you have to ask the other travelers in line to let you go ahead. There should be a better system. Passed passport control and the gate was at Z69 to the other end of airport. Ran there out breath, I was last person to board due to a mechanical:electrical issue plane took off 2 hours later. Lufthansa need to a better job with international connecting flight. A 1-15 minutes is not enough considering the doors typically close 15 minutes prior to take off. So the window is reduced to 1 hour with all you have to go through with a slight delay it is not enough time. The crew on the flight was excellent and received exceptional customer service.

Keep an eye on your seat assignments - ESPECIALLY if you paid for upgraded seats - the airline moved us out of our prepaid seats THREE TIMES and I could only resolve it by calling customer service - who was very helpful. Expect to carry your bags down several flights of stairs for boarding on the tarmac.

Everything was great…Flight Attendants were specially friendly and helpful.

Unorganized, late and they lost my bag for several days.

Flight took very long to even get checked in for, everything was late and written out by hand. My luggage was lost for several days and it was the most unorganized flight experience of my life.

It's the shortest trip one could get from BEG anywhere, so it was fine.

They had lost my ticket and despite showing them the confirmation email with the itinerary and receipt of payment for the flight they could not put me on that flight and rescheduled departure postponing it by a whole week

Long delay (6 hour late departure, not informative enough to provide up to date info on flight, poor food quality

Plane was late causing me to miss connection. Flight the next late causing me to miss the rebooked connection. Air seberia I think is more late than on time

Plane was old. Seats were hard and very close together. No in flight entertainment.

Very poor embarkation in Belgrade , employees not friendly, not well organized. The flight was delayed by over 2.5 hours and the employees at the air Serbia desk at Belgrade were unhelpful, disinterested and all appeared more concerned about their snack (all were munching something) than assisting passengers

They didnt let me do the check in online. That was terrible cause I was coming from another country,so I had to go oit the airport and go un again through controls. They Also made me pay more for my bag which was very light. And the personal was not so nice.

It was not communicated in advance by the airline, but we needed a PCR test before boarding.
