Easy. As one example, a 4 day pairing of flight attendants from PHX could layover in PHL on day one, fly the next 2 days with a PHL pilot crew, and end up in PHX on day 4.
What you just stated is NOT an example of pilots and flight attendants flying the same pairing. Just on first glance, the flight attendants are on a 4-day trip, while the pilots are on a 2-day trip. That is DIFFERENT trips no matter how you do it at UA.
