Playing the devil’s advocate role here, but I believe that the addition of the new OW members JL, RJ, & MA to be a minor improvement at best. Let’s look at what each airline brings to the alliance.

MA-1 daily North American flight to BUD and 3 times per week BUD-BKK flight. If you don’t originate in either NYC or Toronto, one is better off going thru London or Madrid to European destinations. It is still 2 or more connections to get anywhere in Europe. The business class cabin appears to be equivalent to what Aer Lingus offered. I believe that it is priced accordingly.

RJ- 1 daily North American flight to AMM and the schedule is so bad that in most cases one must overnight in Jordan to go to any onward RJ destination in the Middle East, India, etc. Plus their improved Crown class is not even an angled flat-bed in business class. According to the RJ website, they are still using A-310 wide bodied aircraft. Definitely not up-to-date.

JL – Much better long-haul options from Europe and USA. Plus JL has destinations in China that are currently not reachable on OW (until Dragonair joins OW). Again, the schedule is not favorable to connections, as most flights from the USA arrive in the late afternoon, while the flights to Asia usually have departed for the day.
At least the business class cabin from the USA has the new flat beds, though within Asia it is more like CX’s regional business class. But JL is still suffering from OW integration problems. I wonder if that is not a harbinger of future problems.

I do like the addition of LAN affilates, LAN Argentina and LAN Ecuador to OW. Plus Dragonair once they can get their act together. Looks like end of 2007 though.

The addition of IB's IAD-MAD and EI's IAD-DUB flights make the MA and RJ options less then desirable. And, yes I know that EI is not OW, but for an AA based flyer, not a big deal.

I think that the addition of Eithopian Airlines and/or Gulf Airlines instead of RJ & MA would have better choices.

Flame away.
