In your example we could lose 1 transatlantic flight (8176 block hours) and another 28,833 from other theaters and still be in compliance. How is this not a huge give?

687,000 - 650,000 = 37,000

37,000 - 8176 = 28,833

28,833 / 8176 (1 trans Atlantic flight equivalent) = 3.5 flights

In your example 1 trans Atlantic flight plus 3.5 equally long flights from other theaters = 4.5 international flights. This is the amount of reduction allowed and still be in compliance.

8176 / 365 = 22.4

22.4 / 2 for round trip = 11.2

11.2 is a long transatlantic flight so the number is more like 5 international round trip flights lost and still able to comply.
