Many thanks, sounds plausible as some southern european bases have less based aircrafts in winter compared to summer.
Expected BTS, FKB and NAP to have at least 2 based a/c
GRO was one of their biggest bases and now down to 1.
Missing: Faro + maybe summer only bases: Bournemouth, Brindisi, Corfu, Ibiza, Lamezia Terme, Zadar
Bases in Spain, Portugal, Morocco and Eastern Europe get more aircrafts, less in UK (EMA, LPL, BRS, LTN) and in Germany we see a shifting from smaller airports (NRN, HHN, BRE) to bigger ones (CGN, FRA, HAM)
