First impression was positive: a great calendar for selecting dates. But, unlike website, no clear way to select travel preferences (business class, for instance) ... Must be there somewhere but shouldnt have to play detective. Search results for flights lead to a map that takes up 70% of the screen that shows route ...with flights offered squeezed into sidebar. Possibility to sort fly gets but not to inquire about prices for economy plus or business.
