Over the past 2 weeks I have flown:

MEX-LIM-SJO-BOG-MEX (TA/LR/AV mix) and currently wrapping up MEX-PTY-MGA-GUA-PTY-MTY (CM).

The flights with TA and LR posted out of sequence and took up to 12 days to post, AV took 48 hours. CM hasnt even posted yet which surprises me since they apparently use backend software from United Mileage Plus which I thought was quicker.

As far as comp Star Gold upgrades go, CM and AV absolutely do not do this. However, one of my favourites, TA/LR did, in fact, twice. I received an upgrade on the long MEX-LIM and SJO-BOG and didnt on the LIM-SJO because the cabin was full which obviously was fine with me. The meal ex-MEX was awful, truly awful, but the meal ex-SJO was great and the cabin crew were also great.

The CM saga is ongoing. I had real trouble in MEX getting lounge access, as they stared at me blankly like they have never been asked before...perhaps they thought I should take the tram to Terminal 1 and the UA RCC? They were really clueless at checkin and she also entered my Aeroplan number into the PNR wrong since we have those additional useless and confusing parts to our Aeroplan cards...I am not looking forward to chasing those CM miles down.
