I'll be flying to Europe in June. I oriignally was planning on flying to London, but it was $200 cheaper to fly to Dublin. I booked my flights through Priceline and to get to Dublin I will be stopping in London. If I end up wanting to could I just stay in London and not fly to Dublin? I'm concerned that not getting on the last flight, to Dublin, would cause them to cancel my return flight, from Timasoara to Orange County.

This is my first time flying so I'm sorry if this is common knowledge. Not really experienced with this stuff.
