So, here is the real math on the Transatlantic JV that I was looking for.

Through October 16.

Total TA EASK's (in Millions) : 168,414.
Delta Share = 80,410 or 80,410/168,414 = 47.7% of total

If we drop down to 46.5% of the total,
Delta share becomes .465 x 168,414 = 78,312
We lose 2,098 EASK's worth of flying

In that same time frame, Delta operated 44,459 frequencies.
There is a leap day in 2016 so 44,459/366 = 121.47 frequencies/day. Divide that number by two to get 60.736 daily roundtrips.

Delta's 80,410 EASK's/60.736 daily Delta round trips = 1,323.9 EASK's/roundtrip.

2098 EASK loss/ 1323.9 EASK's per trip = 1.58 daily round trips.

Don't know how that exactly relates to the quoted block hour numbers from the Contract FAQ.

Still awake?
