I am planning on studying abroad this summer (in Prague), and was hoping to maybe travel a little afterwards. I do not know for sure right now where or for how long I am planning to travel, and I am afraid that things will change when I get to Europe.
I have very little experience dealing with flying (this is my first time going farther than Michigan, and I live in NJ), so I was wondering whether there was a way to get plane tickets with a flexible return date (or location), and whether they would be significantly more expensive or not.
Yes, you can get fares like this - when you're booking your ticket tell the agent that you want a 'fully flexible fare'. The very cheapest ticket classes aren't fully flexible, so it may be a little more expensive but probably not too much. There is usually a small charge for changing the date of the ticket, but nothing compared to buying new ticket.
I'm with Magykal, only I found that the difference between fixed and somewhat flexible tickets tend to be biggish, but still cheaper than buying two one-ways.
On a side note; once in Europe, I'd recommend taking trains and, to a lesser extent, busses rather than planes to get around. You get to see more, and it's less polluting.
I have noticed lately, that a lot of tickets are not more expensive, if u buy 2 oneway tickets, rather than a return ticket. At least not if u buy them, on the internet
So, maybe u can just get a oneway, to Prague. Although, u should book your tickets a few months before flying, if u want to get the best prices.
