It will be hand luggage only, yeah. And I think I am flying with one ticket, I have never flown before. I was sent a single sheet via email that lists 5 flights, 3 to Newark and 2 back to Vilnius on their respective dates.
So if I got this right, it is possible to make it in time, albeit it would be very tight, and if security holds me too long, I'd just be given a different flight?
