First off im not trying to have someone find me a cheaper flight, just gauging if this is a good price...

Im going to Europe in June and have been going mad trying to find the best deal. This is my plan-

fly out of orlando into london
travel to madrid and fly out of madrid back to orlando

Ive seen tickets around 800 and sometimes get them around 720 to 750, but some of them have LONG layovers.

My mom, who is from europe, thinks I can do cheaper. My coworker who used to work for Virgin says I can do cheaper, she gave me some websites but they suck balls.

Do you guys think ill get any cheaper than 720 or I am pissing into the wind? Thanks
