Such a useful service. My flight was at 8 PM, and I needed to check out of my hotel at 11 AM, but I wanted to squeeze in some last-minute sightseeing. Lugging my backpack around would have been a nightmare. I was also traveling to the airport during rush hour, and the airport rail link was completely packed (to the brim and beyond). My bag was picked up from my hotel after I had already left for the temples (you just need to share a photo of your luggage via the website, and you can track it to see where it is). The luggage was supposed to be delivered at 6 PM, but it was already waiting for me around 2 PM (I still picked it up at 6 PM, no problem). Overall, if you have a late flight, I highly recommend this service. Photos of Bangkok just for fun.
