Very unfriendly ground staff at Vilnius airport. I booked my ticket and paid at Tallinn office no mention of hand baggage rules either from the employee or printed on my ticket. I checked in and was told me I could take my hand baggage as carry on. No problem at the gate no problem at transfer gate in Riga to Vilnius. But at Vilnius airport with same hand baggage on my way back to Helsinki via Riga I was harassed by a young lady until I paid 60 Euros to check in my hand baggage because it was 12 kg instead of 8.9 kg. For a 276 Euros ticket Tallinn- Vilnius-Helsinki it's really unpleasant the flight was not full the overhead lockers were empty above my seat. As I did not speak Lithuanian I had less chance than other passengers that were allowed to bring their 13 kg baggage as carry on.
