Ugh. Delta has moved their 3:30 PM Baltimore-to-NY flight to 5 and jacked up the price on the Thursday return another $200 (so returning on either the Thursday 5pm or the 7pm flight will now cost $560 instead of $360).
I mean, I realize why they're doing that. There's a high demand for Thursday afternoon flights. All the consultants (like me) fly then, and most of them will just pay the fare.
