I'll say it again. There is plenty of Russian tin available, and at short distances, they make money. No wait, low lease rate, have at 'em.
Even brand new, the TU-154B-2 is only $16 mil. Only $10.5 mill down to lease 10 of them. Turn them 3 times a day, and you have better than 4,300 seats of capacity, with no line waiting.
