Aimia runs the loyalty programs for several airlines. A couple of them no longer want to be in that relationship and the process to untangle that web is interesting, to say the least. The Air Canada/Aeroplan buyout offer is still on the table while Aeromexico's offer was rejected outright.

Also in this week's show:

* Rehashing an older tale of the guy who scammed McDonald's Monopoly game for years. And his quest for Delta Gold Medallion status.

* The TSA "Quiet Skies" program is all sorts of sketchy

* American is deferring A321neo deliveries, slowing its growth

* An Air Canada 787 made a wrong turn at Narita, causing a 5 hour delay for itself and a runway closure and scores of other delays/cancels for other airlines

* A few more details on the new Marriott program are out

* Delta is confirming new routes guaranteed to have the DeltaOne suites and Premium Select premium economy seating. Less well publicized is the associated downgrade for Comfort+ passengers that comes with the shift.
