C1,
There is a lot of prestige involved with F1, so we make an effort; they won't deal with just anyone who happens to have a spare freighter around. We took delivery of our 11th 400 a few weeks ago, which has eased things a little schedule-wise. Two aircraft back from C & D checks which are also back on the programme. As you mentioned, AFX also do flights for us. So, yes we can squeeze the odd charter in.
