Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.
Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.
Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…
Flight was great. Smooth flying, movies good. Open seats allowed for good stretching.
Come on. A two hour, 7am flight and a small bottle of water and a tiny chocolate bar was provided. No coffee, no nothing. Poor.
Not enough veg food for passengers. I actually did not get veg food and starved the entire flight duration.
The crew on my Frankfurt to Chicago flight were outstanding!! Friendly, helpful and worth taking the time to write an excellent review on their behalf. I would fly Lufthansa again just because of their warmth, kindness and humor!
Overall, the service was excellent, the crew verry professional, and departures and arrivals were perfect.
The staff were so very cheerful and happy! It really made my day to encounter such chipper folks throughout my journey
love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment
The flight delay made the connection a bit tight but that's outside the flight crew's control.
Boarding and flight itself was smooth and temperature during the flight was perfect. It was just overall vibe for long distance flight, felt cheap ( comparing to KLM or TUI that I used recently). Entertainment out of date movies with poor picture quality, no games, flight map wasn't working
Basic, 737 Boeing, business class is just an economy class seat with blocked middle seat (European standard).
Entertainment is nonexistent. Food might have been good, however due to language barriers I didn’t get to have any food. Flat bed seats and layout was excellent. Crew efficient and straightforward, but lacking any western style approach. Not that I’d expect anything else, but one could have hoped.
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.
Delaying more than 5 hours from Belgrade to Tirana Information very rude to questions
It's the shortest trip one could get from BEG anywhere, so it was fine.
I paid for luggage when I bought the ticket but I could not board until I paid for luggage again. The fault lays at the feet of eDreams, the company that booked our flight. Sorry, Air Serbia, but it did affect the boarding process.
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
Kraljevo is very convenient airport. It's brand new, small.and efficient. Great job!
