when you search orbits for flights from bangkok to new dehli next week.. no flights come up.  when you search for june 31st, 1 flight comes up.  when you search july 1st many flights come up..  how is that possible? the earliest projected time that India will reopen it's airport for foreign travelers is July 10 ( https://atcnews.org/2020/05/31/aviation-projected-airport-reopening-dates-across-the-world/ )

I’ll move this to travel.

just cause they are selling tickets does not guaranteee the plane will depart that day or at all.

I'd not be buying any tickets till all restrictions are lifted
