Add a new filter: aircraft/instructor/Required booking hours
This feature would be very helpful for Dual bookings for Xcountry flights.
I would love to be able to narrow down the calendar so that it shows me:
Any timeslots of 3 hours where both the Cessna 172 & my instructor are available.

Definitely a good idea and will make finding an available slot a lot easier than the current "keep pressing next day until you find anything" workflow.
