Left DFW on Wednesday , originally from terminal D (yay!). Got notice of delay while in Cap 1 lounge. Gate was D-17, so no biggie.

Knew to expect a rolling delay- so I check the incoming plane on the app. Sure enough, incoming is late, arriving at revised departure time.

But the I noticed a terminal change in the app. The text and email on the delay had the same revised time but a different gate and terminal than the app. .

Now I don’t know which to believe, soI walk next door to the flagship lounge — sure enough, a no-notice terminal and gate change.

Subsequent texts and emails for the rolling delay continued to show the original gate. Monitors and app showed the revised gate.

As an experienced traveler, I know to always check the monitors, but this is the first time I didn’t get a correct gate change notice. Does this happen often? Is it a DFW thing?
