Despite pushing MPC to issue the tickets immediately, tickets had not been issued yesterday

LAN cancelled the 4 sectors o/n.
('we pushed into the queue, and LAN had a 2 day deadline for issuance, dont know why they cancelled')

Availability for 3 of 4 was not an issue and MPC has reinstated those, but one of the sectors is now available only in coach. I've told MPC flatly that this was their problem, lets see how it plays out- keep you folks posted.
Anyone else have a similar experience? Sny tips much appreciated!

The flights are way into the future and given LAN's record with schedule and other changes, i expect more fun along the way
