Chuck is on the money in #36! We bought a boat on retirement despite a lot of research into an a/c purchase. The freedom a boat gives vs our ability to borrow some very nice a/c from mates made it a no-brainer!
However, Andy_RR's comment about an Oz solution is only partly true. The UK situation is almost a complete disaster as there's no "common" security pass and each airport issues its own. The GA situation is easier than here, though, as they've been left alone [for now.]
G'day
