Great thread. Something else I want to make sure is that does the free checked bag benefit apply to tickets purchased with miles? I imagine it should, it's just not explicitly stated anywhere. I got the card in June, just got my bonus miles and booked a ticket for next weekend, so let's see if it works. Another thing I'm wondering is if the checked bag benefit will work on an itinerary bought with miles before I had the Citi card. Of course it's been much longer than 7 days since I received the card so technically I should get a free bag on that itinerary too? Let's see!
