Just to be clear, I have not omitted anything. Why would I? My friend is a young inexperienced traveler. So when he texted me about the problem, I took the initiative and called AA myself. He likely didn’t know he could check his bag by using a kiosk. Heck, I didn’t even know that since I only bring a carry-on bag when I fly. But we’ve rescheduled his trip for next week and I’ll
make sure he avoids the ticket counter.
