Let's not forget, that come Wednesday he'll be doing delivery runs to Mitteleuropa (AFAIK on the AMS-BUD axis and everything in between), where St Nic's is observed. (and Xmas is misteriously linked to a certain Jewish baby, not a Christian bishop who lived a few centuries after him)

But it's quite possible, that the European segments are on *A, much better coverage.

But on a serious note - this guy has his own private aerial transport, why should he need some commercial flights and related FFP??
