But a nice change of fleet a sustainable business model does not make, as it were. For baby to move over to the Airbus you'd need to retrain everyone from the bottom up. That's not so much of a problem if you're a massive operation like easyJet, but for a small airline like bmibaby, it'd be costly in terms of both time and money. The benefits of a new fleet are obvious - less likely to be tech, less likely to be fuel guzzlers, less likely to be peeling all over etc. but if baby can keep using the tried & tested -300s there will. Obviously they're not as cheap or as available as they were two or three years ago, but the market is still pretty fresh.
