The around the world deal sounds great to me. I like flying commercial too. The only place more interesting than an International Airport is maybe a circus and they have a lot in common. I have met a lot of people on flights and some are good friends now.
Right now you can find amazing travel deals! I am heading to Europe in April to see a girl I met on a flight in 09. I'm taking a transatlantic cruise in April and then flying around Europe. The cruise only cost $578 for a cabin to myself. Crazy cheap right now! I use vacationstogo.com to find cruises and then go to cruisecompete.com to get bids from travel agents. Sometimes they can get you a better price but vacationstogo actually gave me $75 onboard credit so I booked with them.
My first flight is from Barcelona to Lisbon. It was 7 Euros before tax. $46.47 total. Lisbon to Amsterdam for $74, Amsterdam to Berlin - $51, Berlin to Vienna- $65, Vienna to Rome $62, etc. I have no idea how they sell these flights so cheap but I'm not arguing.
http://matrix.itasoftware.com/search.htm is the place to find these Air fares. Your travel agent won't find them for you. You can't book on the site but you can go directly to the airlines websites and book them yourself. Just pack light. In Europe, your bags will cost almost as much as you if they're overweight. Plus you can take 40 lbs here but only about 30 in Europe. Be careful of that.
I just joined Couchsurfing.com to find places to stay for free. I have used AirBnB for lodging before. I meet a lot of great people that way too. Nothing better than having a local show you around. I can actually spend time traveling in Europe for less than my house payment is here. My house payment is under $900.
I used to use a Sky miles card for all my construction purchases too and I could take my family to Hawaii every year for free. If any of you guys have a business I would seriously consider using a Airlines mileage card.
Have a great time on your trip!! Sounds like fun to me.
