Booked last week, so after the changes. The twitter team told me that I would have to pay the bag charges. I might still send a note to customer care and see what they have to say. It would be nice to have more clarity in the purchase process when the marketing carrier and operating carrier have different policies. The Delta agent did comment that the pricing was different than a straight Delta ticket at $25/$25 for the first two bags, instead of $25/$35.
