Yes, I agree, the airline logos is a good idea especially when there's usually 2 charters going to the same place and the endless confusion with the WW/BE EDI's! Also, the ''boarding in **mins'' or ''gate opens **mins'' idea I have previously put forward to airport/handling personnel but fell on deaf ears, but would probably be badly managed anyway - a FIDs Supervisor is needed if anything is to go virtually 100% smoothly.
