On a slightly more serious (and annoying!) note, I have just found out that the PETS scheme - where you can bring in your pets from qualifying countries (most of western Europe) without them needing to go into quarantine for 6 months - explicitly EXCLUDES pets brought in on private flights (it lists only "approved" carriers such as BA).
So, while we will enjoy our new plane and pop over to France for weekends, etc., Fido will have to stay at home.
