So i'm clicking through OpenSkies to faux-book until they want a card number so i can see all their rules and regulations and an odd little incident occurs..

The price suddenly changes. I was already quoted the full fare and fees on two previous pages and even declined insurance. It's a miniscule bump, but it's there. About $7. Anyone know why it would do that and what it's going toward? The new page lumps it into the "taxes and fees" (which was calculated lower on all the previous pages - in particular the ones that give a detail tax and fee breakdown).

If i go back and start over it's gone, back to the old price until I reach that point in the reservation process again. It's only $7 but i'd like to know what i'm paying for.

Any insight?
