As @Devon_Mo_piedmont114, try flying multiple legs in a single flight. A great way to do this is by tracking a regional or domestic carrier’s plane, particularly low-cost airlines that typically fly their airplanes multiple times per day. Usually, planes bigger than a 739/321 and maybe a 752 will only do 1-2 flights per day, unless they’re doing a long haul that has a stopover. A great example of the latter is China Eastern’s PVG-XIY-MAD flight, which showcases another way to improve your ratio: a long haul with a short haul before or after it, so you can fly multiple legs but don’t miss your phone too much during the day.
Back to the first option, though. As you can see, N619NK, the Spirit A320 in IF, flew LAS-AUS-ORD-LAS-MSY-ORD-ATL-MSY-MSP-ATL-MSP-BWI in one day (some legs are filled in according to order of flights)
If you did this, you would have 11 landings for 1 flight.
