Not sure if my understanding is correct:
I will be arriving from HND-LAX-YVR. All segments are with UA
I should be arriving in LAX at T7, have to clear immigration and bags at TBIT, then re-check my bags at T7?
If I wish to use a shower at TBIT * lounge, then I will have to either walk back airside or outside?
I assume, the bags are not checked through, or are they?
