Do you work in IT? They are merging 2 separate systems and also upgrading it in the process which is not an easy thing to do. If it were a minor upgrade then yes, this would be unacceptable but this is a one time process to get all the frequent flyers on the same system.

Do I need to work in IT to know that a company can run redundant systems until they workout the integration of their middleware and database integration? Any reason they couldn't run concurrent systems until they finished testing their integration and done a competent QA trial? Clearly they didn't stress test their integration before flipping the switch. Integrations like this happen all the time. And to answer your first question, no, but I've worked for a big five consultancy doing massive ERP integrations and installations for much larger companies than this.

As somone who does system conversions for a living, I could tell you stories that would make you absolutely cringe about how things can go wrong.

I'm sure they're not exactly happy with the ongoing issues, but put the impact of this in perspective. What is not functional? People's online access to their FF accounts.

--Customers can still use the website for all other functionality
--Customers can still access their FF information via the phone at no cost
--There is no impact on any of their delivery channels for selling the product
--There is no impact on the operation

It certainly isn't a good thing, and it doesn't reflect well on the image of the company. And the longer there are problems the more unhappiness there will be. But this isn't the type of event that costs them sales or creates havoc at the airport.

SWA recently went through about a 24 hour period when their whole site was down. That kind of problem is a failure, not this.

I've probably jinxed them by what I've said...watch the whole site go down now for 48 hours. (That's a different story!)

Have not had any sign-on or access issues since mid-afternoon.

(hopefully not the kiss of death saying so.)

On-line booking is again experiencing problems for E190 seat selection on Classic fares; it only displays available seats same as Economy, starting with row 11, instead of at row 5.

The profile system is currently unavailable, please try again later.

I just got in now...give 'er a shot again.

Flights going MKE-LAX trough MCI, and back seem to have disappeared from the booking engine.

They are available on Travelocity.

I am flying that route later this week, checked with Frontier. They seem to have no explanation.

Outbound appears to have been restored, return portion still not displaying.

I can get into my profile, with no problems.
