So I made a big mistake and decided to fly out of LA to Hong Kong. At the time I thought I had a ride down to the LA area, but unfortunately it fell through. Because of this I decided to book a flight out of San Francisco to catch my international flight in LA.
Thankfully I planned ahead and made sure I had at least 4 hour lay over in LA to find my international flight and to relax before the 21 hour flight to Hong Kong. Thankfully I am backpacking, so nothing is going to be in the bottom of the plane. The only thing I am worried about is do I need to go back through security and go through customs? or can I check-in on my phone? I do have an E-Ticket. I am going from Delta to Korean Airlines.
