The best evidence of reroute pay improvement is bidding. Pre C19 senior pilots (top % that could) bid to avoid sits in ATL because you would be rerouted for no extra pay into a longer duty day with a shorter less desirable layover destination. Now pilots do everything they can to be potentially rerouted, including a complete 180 in bidding strategey because between EDP, SIT, and reroutes ATL sits are some of the most lucrative trips. You're welcome.
