For the first three months of 1969 there were 22 weekly direct services BKK-LON
45 years later, there's now about 28 direct services BKK-LON per week.
Truly an impressive growth rate !
OK, so there is the minor factor of flights now being non-stop, taking half the time, having more seats per flight, and all being end-to-end terminators rather than calling at all stations...
