Good post, but I respectfully disagree on some points.
They company should asked ICAO for a completely new call sign, one that is not divisive. "Blue Tail"? "Blue Streak" is apparently available again. http://webcache.googleusercontent.com/search?q=cache:_PjI-rG1V7AJ:www.airlinecodes.co.uk/callsign.asp+icao+callsigns&cd=2&hl=en&ct=clnk&gl=us
The blue top colors had prestige and panache. And could be spotted a long way off.
Parents have to pay svc charges (plus taxes); a trip to Europe can be well north of USD200. Sometimes a ZED on an OAL is less expensive. I would be not against the old choice between USD 50 annual fee for each person on the term pass (there was a cap for large families) for unlimited free travel or a svc fee for each trip.
Blue Streak is the Call Sign for USAirways Owned Express Operator PSA , so it is not available.
The call sign goes back to the Days of JETSTREAM INTL which the Original Piedmont Purchased and has since changed its name to PSA.
