Budget carrier Ryanair fly into Kaunas airport, around a one hour bus journey from Vilnius. There is a minibus that meets flights and does the journey into town, then dropping off at three central hotels. Price is 25lts per person, well worth it for the convenience.
Exit the terminal and it's parked on the right hand side of the carpark. Recommend booking online before you get there to ensure a seat.
I am mostly everytime use buses or trolleybuses - cheap and convinient. But the problem appears - sometimes it is hard to get fastly to another part of city and then minibuses can help. It is ike cars, fast and convinient. A price a bit differ - it is more expensive - it can be taken from 1 Lt to 2 Lt mostly always for trip (0,3 - 0,6 euros).
One more thing I should mention - you should say for minibus driver where you want to get out.
There were scheduled mini-buses like this one on my picture in Vilnius. They stopped at public transportation (bus and trolleybus) stops. The itinerary was written on info table behind the front windscreen.Excuse, I didn't use them but I noticed that their passengers pay a driver.
These are like taxis as they can be stopped anywhere, but they goes on pre-designed routes. Ussually route number is the same as one of bus/trolleybus it dublicates, but it is not always so. You can recognise shared taxi, which is ussually a not large minibus (but could be larger buses too), by route number either beneath front window or on doors. Tickets costs either 1 or 2 Litas, depending on werether car you are using is new or old. You can't buy them in kiosks, only from mini-bus driver.
Minibuses are very popular in Vilnius. It's a good alternative for municipal public transport (buses and trolley-buses). Minibuses are fast, more comfortable and warm in winter. If you wanna get somewhere fast then you should choose it. Price is 2Lt (~60 Euro cents). You also should know that some call them "kamikaze". That's so because minibus drivers usually ignore rules of road and drive like crazy. But don't be afraid, they're usually professionals so there's nothing to worry about.
