The winter schedules are slightly busier at Liverpool than East Midlands.
Currently, exlcuding Ryanair (which is the only airline at both airports which has not yet finalise it's summer 2013 schedules) East Midlands has close to 50 departures on the weekdays and about 35-40 on the weekends whilst Liverpool sits at 30 maximum for all days of the week (EasyJet are slighlty down in 2013 at LPL with one less aircraft than 2012). As Ryanair will have a very similar amount at both airports with about 20-20 daily departures, and as far as I know EMA will be marginally larger than LPL which is a first then EMA will have about 70 odd departures on the weekdays and about 55 on the weekends and Liverpool will be around 50-55 every day.
EMA is much quiter on the weekends because FlyBe do a lot less flights and BMI Regional and Eastern do not fly at all on Saturdays and only have 1 or 2 on Sundays. Basically, East Midlands will be above Liverpool next year without question, and we are even expecting more growth by BMI Regional so it may be even higher for EMA.
As LBA, they are about 50-55 departures on the weekdays without Ryanair, so would expect maybe 65 departures in total once they are included. Not so sure about weekends though, but again would expect them to be much quieter than the weekdays. Although 10 more departures a day from LBA than LPL on most days, LBA has a lot more smaller aircraft such as Embraers, Fokkers and Dash 8's so not sure whether they will overtake!
