Do you have anyone at home that is up that early?
My sister and I always check each other in the day before our departing flights. When you get to the airport they will print your boarding pass again when you check in if you tell them you don’t have it. (Once, I told them we had lost it, the second time I just told them I didn’t have it…they didn’t care)
Good luck and have a great trip!!! Hopefully, April will be here soon!
