Fortunately surprisingly quick, that queue. About 30 minutes in a queue to check in. Almost caused a diplomatic incident as the young 4sum Chinese group took my legs out from under me for the 3rd time. I pointed out that I was behind them ,(gesturing to the couple in front), and that the Chinese people were behind me and would not be getting infront. If they wanted to offer me their trolley as a wheelchair I would be delighted...
The first two security areas had signs saying "full, use area 3." So I did. 10 minutes to get through security and immigration.
Now sat in BKK airways lounge, eating puff pastry pizzas.
