I can confirm there's definitely no trouser option for Flybe girlies. And I have it on good authority that there never will be as long as the current management team is in place - they believe that skirts 'project a more professional, full-service, customer-oriented image'
I would actually go along with that. As a passenger I think Flybe's uniform does give off a more professional image than some of its rival loco's and would hope that the uniform will stay as it is.
