V-Flyer

Notice the past week VS400 has had a 340-300 and a 340-600 tonight operating it when it has been a pretty steady 330 on it for the past few months. Any reason for these changes? I'm flying it in July and would prefer a 330 which I took as a dead cert but now

Could be because the 330s have been going to Malta for routine maintenance at the moment

Does anyone know when the 340-300 non-AVOD crates will be retired?
