I am an american citizen, my son has dual citizenship (USA and AUSTRIA) my husband is an Austrian citizen, the rest of our group( 4 other persons: Family) are Amercian Citizens. Can we all check in together? Can we pick one line or the other(whichever is shortest) and check in instead of everyone waiting in their respected lines?
I thought it would be easier if I checked everyone in so they could look around the terminal and relax. If the line for non-US citizens was shorter, could my husband check everyone in? Any insight would be helpful! Thank you.
