that sounds pretty young for both. almost all pilots of seen have plenty of grey, although the other day i saw a woman pilot, i was going to ask her if she flew b52's.
24? Not really that young.
There was an issue of Airways Magazine a couple months ago in which they talked about the first female pilot for AeroGal, a Central American airline, who flew her first flight for them in a B732. She was 19.
In this month's issue of Airliners, there's an article about Royal Bhutan Airlines, who is the only airline service VQPR (Paro). They are using A319s for their routes in and out of that airport, going to India and Nepal. The approaches to that field make Aspen look like a walk in the park. VQPR has no instrument approaches, so if the field isn't VMC, the field isn't open period. Anyway, they just had their first female pilot fly out of there and land back there, and she is in her early 20s.
Don't let age fool you. If they're qualified to be in that left or right seat, trust them. they deserve it.
