Tealady is a bit confused lol. The February break is being considered (Most likely starting in the 2020-21 season), but the break itself won't "extend until May," rather that the full season, along with the month haiatus (or however long they would break for) would extend into June. I am very sure there would not be a huge break from Feb through May. ;-)
And then, the ABT season would be shorter than it is now. (5 weeks, I think?)
This, in addition to the possibility, starting perhaps next year, of some Sunday performances throughout the season (with Monday nights dark, I assume).
