Between December 26th and January 4th, I am planning a trip to Europe using miles. I am finding plenty of flights over there for 27,500 miles...but coming back is proving difficult, I am not finding anything on January 4th under 50,000 miles. Does anyone know the best ways to search?

I am open to where I travel and fly back from, I am just trying to get back for 27,500 miles too.

Any suggestions are greatly appreciated!
