Hi, we just did Qantas to LAX connecting Westjet to Vancouver on Tuesday this week. A couple of comments, we were booked on Qantas boarding passes all through to Vanc. We were able to book baggage all the way thru. Picked up in LAX and dropped off immediately. Mister & I are both Qantas Club so we're expecting to get into Q club in LAX Terminal 5 as we had 5 hours waiting. We checked back in thru security to airside, able to because we had Q boarding passes but were informed by the lounge that even though Qantas booking, the Lounge would not take anyone on a Westjet flight as there are no reciprocal arrangements. They were very firm. The First class lounge has the same rule, I heard it from them directly. So, I am not an expert on higher fare or Status options but if you have access to other lounges, eg flying first class with Westjet you might get Delta lounge, I would explore those other options. So, we stayed airside in T5 as it was comfortable, then wandered down to T2 as per the boarding pass however the flight leaves from T3. The walk is refreshing after the flight from AU not too onerous.Interesting to see TSA refuse someone based on terminal alone! This could perhaps be a capacity thing as the TBIT security checkpoint is massive from my memory and hence has the capacity to deal with all sorts of customers. What I do recall a representative from the TSA once saying when people were frustrated with the long queues at certain airports was to do as I said, (i.e. check the MyTSA site to see which terminal has the minimal wait time and clear security through there).
Hopefully that's ample time, and given WestJet's on time performance I wouldn't be surprised if that 5 hour layover turns into 7 a hour one!
Joking aside, I reckon the QF F lounge at LAX is pretty good when it comes to things like food, showers, etc.? If I was in their shoes (and I'm not in their shoes BTW) the first thing I'd do after a long flight like that would be grabbing a shower at the lounge!
My other observation, if you are departing on QF11 it consistently leaves 1-2 hours late. You can see the history on flightaware. We were about 1 hr late departing Syd.
Hope his helps. Enjoy yr skiing. We head to Whistler tmrw.
