I would like to travel to Lithuania this summer, and have looked at Kayak to get an idea about the range of prices depending on dates. Are there different/better search engines for flights to a not-well-travelled European destination (at least from the US)? Is this a situation where I should try and bid for an airline seat (I had never heard of this until I started researching my trip)?
Also, I would appreciate advice on how to travel around Lithuania by bus, i.e., which bus lines are the best, whether or not to buy bus tickets ahead of time, is Bolt a better option in some cases, etc.
