Looks like the "soft-open" of the BKK satellite terminal will be on September 28, which just happens to be a day I will be passing through BKK (HKT-BKK-TDX).
Do we know yet which flights and/or airlines will be using the satellite terminal?
I will be back on October 18 (TDX-BKK-DOH) so that should be an even more interesting time. I will try to post photos if things have changed.
