I will be traveling CX from LAX-BKK. the flight arrives at 10:45 am. My next flight is a 5:30 pm flight from BKK-BOM, which although on CX, is booked on a different ticket/itinerary. As an AA PLT/OW Sapphire, I believe I have access to a CX BizClass lounge during my trip. For those who have been through BKK:

1) Can I access the lounge without having to go through immigration and customs (because I have two different tickets LAX-BKK and BKK-BOM)?

2) Can someone tell me what the lounge is like (shower facilities would be fantastic!).

Thanks for your help!
