I stand corrected Sir. Due to your insistence I found Big C open y'day (tucked well away from the main road) after a fair walk in the blazing sun, so many thanks😄
No return flight was asked for when I applied for 60 day visa and neither the airline or Thai immigration asked. I had bought a return flight on day 60 though just in case😊
Qatar called two days before the flight to say arrive 4 hours early as some people had missed flights due to long security queues at LHR.
I was advised on here to check in online (from 48 before) and print boarding pass beforehand.
I arrived 5 hours before, no wait to drop off my bag and through security in 30 mins. No forveveryone but suits me😃ps Strangely no security before 2nd flight🤔
