Hey guys, I'm flying to Pittsburgh by way of Amsterdam and Detroit from Glasgow in a month and I'm totally lost about what goes on. I'm sure I'll have to check in or do it online or whatever, and I know how to check in a bag as I've flown domestically before. But what's the process for layovers? Do I come out of arrivals and pick up my bag and head for departures? Or do my bags just magically make it onto the next plane? Also, will I have to go check in again for my next flight or can I just go right through to security? Any advice would be very welcome here. Thanks in advance!
