Flight options.... There are a lot of different options for you to purchase tickets. You can go with the large corporations like Expedia, Travelocity, Priceline and Orbitz. They don't always have the best fares(that's why I say to check around first) and are probably not your best bet for customer service. They can sell you tickets, hotel rooms and auto rentals, but they probably won't be able to answer a single question you have...that's what happens when you're working with a robot.

Another option is to get a low fare to Europe and then fly between European cities on the low-fare airlines. You can get some good deals that way, but remember- you'll want plenty of time between flights because neither airline is responsible for you missing a flight.(that translates to- you may have to pay for a new flight or a hotel which will wipe away any savings you may have-so plan lots of time between flights). Another problem with mixing flights could be the baggage allowance- Transatlantic flights usually allow you 2 70-pound suitcases plus carry on while the inter-European flights allow only 20 kilos(24 pounds)- they usually don't-but if they choose to make you pay for your "excess weight" it could cost more than the ticket and more than the money you saved...so be careful with that. It can save you a lot of money, but beware of the risks and use your judgement.

In past years I have had luck finding a low fare to somewhere in Europe and then either taking a train, flight or ferry to my final destination. Two sites that can help are European Flights and Eurail. I don't have any info on ferries, but you can probably do a Google search below....

Anyway...search away for the best fares, let me know what you find and I'll try to advise you on your best options..
