My bet is Afghanistan says fine....but they can only handle six planes a month (1,200 passengers). You can do the math with 150,000 Afghans in Germany....but it’d take more than 10 years to achieve complete success.
My math says it’d take a minimum of 750 flights to take the 2015 crowd. Somebody in the private airline rental business is going to make a ton of money.
Your math doesn’t factor in other transportation routes.
Mexico doesn’t say fine so why would they?
