The Curt Jester outlines the advantages of travelling with the Vatican Air Service... I particularly liked:
When boarding you always have to enter through the "narrow gate."
Dominicans, Franciscans, Carmelites and males from some other orders are eligible for Frequent Friar Miles.
Flight insurance includes a fund that will pay stipends to a monastery of your choice that will have Masses said for you in case of a fatal accident.
If Vatican Air loses your luggage St. Anthony is immediately invoked.
