It's tight but probably fine if your bags are tagged and you are able to power walk. It may be lots of walking to immigration, then to T6. Not the craziest thing.

Someone just asked about AS bag drop at TBIT on the AS forum, which seems to be "yes" if it's tagged - https://www.flyertalk.com/forum/alas...nnections.html

I've found GE at LAX to be consistently fast. I think clearing TSA at one of the downline terminals (whether T4/5/6) is usually faster than TBIT. The longest part of the layover will likely be waiting for bags, hence having them tagged and dropping them at TBIT is probably most important. Alaska also just moved the checkin cutoff to 50mins (boo).
