I personally think that AA does a good job with its Flagship Program and its premium products in general. The ground experience is already better than what AA's rivals offer and I find the premium cabins to be more consistently comfortable than DL, UA, or AS. I find even the older J cabins to still be quite spacious and comfortable for longhauls, even though the 77W and 321T are showing their age. When they take delivery of their new XLRs and 789s and complete their retrofits on older aircraft, they'll easily have the best hard product among US carriers.

I believe there's a huge opportunity here for American to make some small and affordable changes to the Flagship product that could put them on par with their European and Asian counterparts:

1. Attentive FAs that seem to enjoy (or at least not resent) their work. I've had some flawless crews, but there's no excuse for how bad it can sometimes be. I don't need white glove service, but I'll take an AS or WN flight attendant any day of the week. Consistently offering PDB, a proactive refill or two, and clearing plates and trash - that's the only thing separating AA and most international carriers from a service standpoint, but it does make a big difference to the pax experience.
2. Dine on demand menu with small bites for flights over 10 hours.
3. More frequent updates to onboard dining. Besides whatever is going on with their beef, I don't find the Flagship dining to be totally abysmal. However, I think that more frequently rotating in new menus would go a long way to provide variety and liven up the experience. The wine list ranges from awful to acceptable. Stock a few bottles of premium champagne or sparkling and a few of a nice Rhone. I don't need 2008 Salon, but would be thrilled with a $40 pinot noir champagne or blanc de blancs before a 12 hour haul to LHR.
4. More variety in the hot food rotation in the Flagship Lounge, and for trips operating from airports that lack Flagship facilities, provide a premium drink voucher and complimentary hot menu item at the AC if flying on a Flagship itinerary.

This may be wishful thinking, but seeing how AA is investing in their cabins and lounge experience, there's no reason they shouldn't vie to have their Flagship offering taken seriously as a premium product. What do you think?
