So I just booked my flight to Bangkok! I found an itinerary that works for me and allows me to maximize my time in Bangkok. I'll probably be spending the last part of the day at a mall like Siam Paragon, which closes at 10 PM. Are there any malls that close later? After the mall closes, I would like to grab a quick bite before taking transit to the airport. What's the latest possible transit option to BKK for a 4 AM flight? Since this flight isn't part of any alliance, I won't have lounge access through my FFP. I do have a Priority Pass, but I don't know if any lounges are open in the wee hours of the day. If not, then I definitely want to grab a meal before heading to the airport.

Merry Christmas!
