A few changes would make it a lot better

Needs to:
Remember user.
Save upcoming flights to avoid repeated entering of booking number.
Provide boarding passes in app without email.
Provide Voyager account data and status.
Provide a voyager card that actively changes with status in passbook.
Allow search and booking of flights in app.

Just take an example from Delta or BA! Changes are overdue!
