Have you seen the prices Titan charge for their aircraft at short notice? I don't blame GSM for not going with them!
GSM have been better at covering tech aircraft than bmibaby did, at least GSM will position in another aircraft to cover as soon as one's free - WW never did that.
4567 - GSM are getting rid of both B733s, as well as the two remaining B736s, so I have no idea what they'll give us if they're still gonna be here this time next year.
