Here is a problem that I have noticed since last Fall and have pointed out to DAL several times, but nothing yet has been done to correct it--I just tried again before posting this.

This is when trying to book an international (maybe domestic too--haven't tried that) itinerary on delta.com--using fare class M or higher (it may be a problem with other fare classes or higher as well--I use M for the PMU upgrades). I make my request, pick my flights, they give me a fare quote, I confirm with SMS that the Z inventory for upgrades is available, I enter my
four digit security code for my stored credit card, but then instead of getting the confirm/purchase page, I get a page that says "the fare is no longer available." The fare is actually available--and I get it through calling SMS and getting transferred to web support. Still, that's a bit of a pain and I'd rather just do the whole thing on line (other than executing the PMU upgrade with SMS).

I have an up to date Dell computer--XP Professional, an up-to-date version of IE (7.0573.13) so I don't think that has anything to do with the problem (I originally got emails back from Customer Care saying basically there is something wrong with me or my computer). Further, this same issue occurs for my account, my wife's account, and also on her computer and her laptop. Even further, others posted on FT last Fall about having the same problem.

I have received emails last month from DAL saying they were aware of the problem, but it has not yet been solved.

Thanks for starting this thread and looking into these sorts of issues.
