8 of 14 E-195-E2s were out of action in the first week of January due to problems with their P&W engines. That’s bound to cause disruption in the aircraft normally allocated to the routes they fly. All but one of the other Embraers (E175, E190) were in service to cover which may explain the prevalence of E175’s at LBA.I was reading an article the other day that said KLM is have problems with engines on the E jets. So that may be a factor in what type comes into LBA.
