Thanks Goldorak

Looking at the individual flights on the BKK-CDG-LHR at the begining of September, it is the BKK-CDG flight that does not have the option to 'But a ticket'. The CDG-LHR flight, just like the LHR-CDG and CDG-SIN flights, has the 'But a ticket' option when they are searched in the AF online timetable (https://www.airfrance.co.uk/GB/en/lo...es/horaires.do). Does they imply the flight on that day has been taken out of the reservation system and will be cancelled?

Even though this is for a flight at the start of September AFKL refuse catagorically to refund tickets when they cancel a flight (which I experienced from my cancelled KL flights in April). Should I just request a voucher now and assume the August/September holiday is a no-go, rather than waiting for AF to notifiy me 2 weeks (it at all) before departure that the flight is cancelled? That way at least the voucher will expire 12 months from now to wait for its exiry and get the cash back, rather than wait further 12 months from August 2020 to get the cash back?

From what I am reading in the Thailand forums here, although nothing is confirmed yet and things change quickly, is that Thailand might mandate 14 day quarantine for quite along time (currently no entry to non-Thais and 14 day quarantine for returning Thais). If that happens no tourist would go to Thailand.
