Either a bunch of 737-800 & -900s Maxs, 50 plus 50 options, tied in with the EK 777 order (it's being paid for from the same purse of course).
Or, a bunch of 320/321s, re-jigging the EK A350 deal with a few more 380s for EK, as I suspect those 350s won't turn up. Either way a strong bargaining position for a good deal on aircraft.
