Get to Europe, train-it-up to your hearts extent.
Europe is about the size of an average Brazilian ranch so it’s probably more of a waste of time to involve airports. But our resident travel expert
@Adler would have more relevant information than I would.
By the time I saw this post it had turned into an Octoberfest thread, and I figured I was too late.
Trains are expensive, busses take forever, ZEDs are cheap.
I have short legs and would rather get somewhere 10 hours earlier by riding a coach ZED than nonrev maybe maybe but probably not getting first class. Lufthansa, Austrian, and Air France will get you just about anywhere in the world. Book a ZED, get a ticket for something in the back, hand a flight attendant $6 of chocolate from Trader Joes, and you just might find yourself in business class. The smilie faces are usually pretty accurate. Hundreds of thousand of miles on ZEDs, and I've only not made a flight twice; once in Hanoi when an employee showed up last second with a litter of kids, and another trying to get to the spring break capital of Europe, and even then the gate agent apologized saying the captain was in a bad mood and wouldn't let me in the Jumpseat. Speaking of which, yea, a lot of those carriers will take you in the cockpit.
All that said, if you know you're dates well in advance, you can buy some tickets on low cost carriers for less than the train ride to the airport.
