Given the US merger is likely to be completed this year, there will definitely be implications for the new FF program which will continue under the AAdvantage name. Looking at the US program, some might like its current upgrade policy for North/Central America and the Caribbean which is unlimited automatic upgrades into any open F/C seat (at time of booking for Y/M fares, 7 days for Chairman Preferred, 4 days for Platinum, 3 days for Gold and 2 days for Silver) for all elite tier members. Of course, AA limits this approach to ExecPlats, and other elites must use 500s or miles. (All must proactively request their upgrade too.) Chairman elites only get 2 SWUs compared with the 8 ExecPlats get. So as an ExecPlat, taking up the US upgrade benefits will be a major downgrade. What I like about the more exclusive AA "domestic" upgrades is that there are often empty seats in F/C at departure. This gives the front cabin a more relaxed and exclusive atmosphere and provides better service than a full cabin as is always the case with UA and US. But more important, if my flight gets rerouted or itinerary changes at the last minute, I have a very good chance to keep my F seat on the protected alternate flight(s) because of the limited upgrading policy. This seldom happens with the other two airlines since they tend to fill all the front cabin seats in advance with lower tier elites if they run out of top tier ones. And of course 2 is a lot fewer than 8 SWUs! And US has four tiers of elites compared with AA's three. As UA did after the CO merger, AA will have to add an intermediate tier between 50K and 100K. This would actually be good because it does delineate 60K and 90K earners in a way the current system doesn't. (And the 75K tier appears to be the trend since AC has just adopted it too.) Just a few speculative concerns. Your thoughts?
