First glance, both those say flight training / student /school.
Think it could still work for our needs; dry lease (pilots/plane/passenger, specific trips) and government pt91 work (several planes / several pilots/days to weeks missions), need text reminders to pilots, passengers, management.
There’s several options. One plane I fly is on bookourolane.com. Don’t waste your time there, it won’t do what you want.
Our plane is on aircraftclubs.com. Cheap, will do some of what you want, easy, and no customer support.
That really leaves Flight Schedule Pro and Flight Circle. The two will what you want for about $25/mo per plane with payment pricessing incorporated if you want. Flight circle offers a cheaper option with no billing.
Our club will switch to Flight Circle this year; it’s well documented, has fantastic customer support, and will get us out of money handling with electronic billing and payments, to include auto pay by ACH, credit card, or charge to an account that can be paid by zelle/venmo/whatever.
Both have maintenance and reporting, FSP charges more for advanced maintenance tracking and reporting. Flight Circle will give you a 30-day trial while FSP only 7-days.
ETA: pax manifesting and contact is something you’d have to talk to both companies about, but I could see some creative ways to get FC to do that, I think.
