Joanna,
It may be possible, but last year I contacted Island Wings (Michelle) for Misty Fjords flight at the beginning of March for late July cruise. Only available time made it a bit of a tight connection for ship's departure and all worked out well but I did have to remind her of time constraints. I can dig up the details re: booking time and $$ if you'd like - be happy to! It was our favorite excursion - good weather, beautiful scenery and she's very impressive.
