We're going on a cross country flight next week and will be taking our convertible car seat (not the main one).

Question #1: I really don't want to gate check it. We'll be flying from Atlanta and the airport is busy and big and sometimes the gates feel like it's 200 miles away (and this was before baby). LO will be in her umbrella stroller which we are gatechecking. Should we gate check it? Has anyone just checked it in with luggage?

Question #2. I also don't want to buy a bag cover and use it only like several times. Is there anything else I can cover the car seat with? trashbag?
