I am flying into LAX on Alaska Airlines which I believe lands at terminal 3 (according to the terminal map). They I catch a Delta flight to Kauai. I do not have gate assignments yet; but according to the terminal map Delta is at terminal 5. The flight was set up with Alaska Airlines all the way but was changed to include a plane change to Delta Airlines at LAX. If I have to change terminals is walking feasible? I have about a 6 hour lay over; so plenty of time. Or would a shuttle make more sense? Thanks out there.
