This morning, as I was browsing about for flights, I went back to the Advanced Search page and found that the lowest economy fare class available on the page (according to the site) looks like it is no longer T, but instead, E.
ExpertFlyer doesn't seem to pull up any availability for the E fare in revenue bookings, but still pulls it up in the award availability section. The
Delta Fare Class chart states that the E fare is for promotional travel and SkyBonus awards. Any idea why this might've popped up this morning, or is it another website hiccup?
