BTW, when will AA have a merged res system? there is a whole lot of the merger process that is dependent on that step.
seems to me that other carriers had managed to merge their res systems within the first year. we're at 10 1/2 months for AA/US
Yeah, not quite. DL/NW was an anomaly, since both were in Worldspan. There were no incompatibilities in merging the two PNR databases, and only minimal change needed to switch over some of the back-end systems. Sure, there was some work needed, but when you have different departments within Worldspan doing the work, and there's no incentive to drag it out financially, things can move a lot easier.
When you're switching half your operation over to a new platform, it's approaching the same level of doing a system migration, and the lag time between deciding on a new platform and doing the migration is 36 months.
UA & CO did their migration just shy of two years in, and paid a huge price because they rushed it.
WN & FL never bothered with a merge, and it will be approaching a three year process give or take for them to get out of SAAS.
AF & KL merged in 2004, but didn't actually merge their res systems until 2011 or 2012.
So no, "within the first year" is nothing but fantasy when you're talking about a migration. The only way that can be shortened is if the basic PNR is identical, e.g. two Sabre customers merging, or if you do a point-in-time cutover like Airtran did, e.g. all bookings involving travel past March 1 are done in the new platform, with a date set so far in the future that you don't have to migrate bookings.
It's a servicing nightmare, but it's a relatively low risk approach that buys more time to get all the airport systems ready to switch over.
