How are people flying long distances to Thailand given airport connection restrictions? Leaving from vancouver seems virtually impossible as my travel agent keeps saying system reads “documentation insufficient for journey... etc...”. In other words seems like places like Taiwan aren’t allowing for connection flights to reduce risk... is that so? And every flight path option from Vancouver has an overnight somewhere so what happens in those instances?

To summarize what airports are allowing connections and overnight stays? (Most flights seem to go through Taiwan, Korea, Japan... might have found one through London etc...)

Thanks for any insights!
