Thanks for this posting!
It is strange that they terminate the code share agreement on June 25 and the lounge access on the 1st...
The good news is that for me, it shows that AC perhaps wants to move faster than expected into integrating CP in *A.
The summer season will be strage having acces to *A lounge worldwide but not being able to redeem miles on AC partners and in the same time still be able to get miles on AA but with no lounge access :-(
