Irritating - There is one seat available for $311 in a given market. Expedia and AA see it. Travelocity doesn't, quoting $433 for 2 available seats on those flights although the traveler total is set to "1". Is this a systemic issue with Travelocity, or just slow response to a lowered fare? So why don't I just book elsewhere? Because, if you want to use US Bank Flexperks rewards points, you're locked into the Travelocity engine. A Flexperks annoyance.
