Don't find folding the letter size BP too much of a challenge. Best part is the gate agent's reaction to the often unusual paper that happened to be in my printer at the time of printing. Flourescent lime green always seems to get a raised eyebrow or two.

Definitely dislike the thermal paper, though it's better than some of the paper stock I've received from B6, which is as flimsy and easy to lose as a pay-at-the-pump gas station receipt. My students have an impressive record of having those boarding passes just flutter away mysteriously before boarding.
