I know I've seen a thread on this not too long ago but can't seem to find it. So please bare with me for asking again.

I arrive at 11:40am into LAX from SJC on UX and transfer to an SQ flight at 1:10pm. Flight from SJC was to have arrived 15-20 mins earlier but just got a schedule change notice and called reservations. The agent wanted to change my flight to the 6:30am flight to arrive around 7:45am into LAX as she said the 1:30 mins to transfer at LAX might be pushing it. Told her to leave it as is right now but any frequent travelers at LAX know if I'm setting myself up for disaster here? Wasn't there like a inter terminal bus tranfer airside that you board by going down a gate and they take you to TBIT directly?

Please any advise most appreciated! Thanks!!
