REG or RES: you call and tell them about the illegal rotation and they may or may not remove it.....as long as not exception to FNGL, then you FNGL and file STS with ALPA.

REG: if they do drop it, they pay protected with zero recovery obligation....free to pick up WS or GS or IA or QS or PSB if you so desire.

RESL no rotation guarantee so no soup for you....go back on LC.
