More good and bad, when searching for flights.
On the price+schedule results page, the breadcrumb indicators (start over; flights; passengers...) are misaligned and overlay the top of the the dates. This using Firefox 3.6.12.
^ The results page now has a Search Alternate Dates link at the top right; when clicked it invokes a calendar selector that lets you choose any new date and re-search without going back to the main search page.
