If you avoid the holidays, winter is the most inexpensive time to fly to Europe. But to enjoy all that Europe has to offer, including pleasant weather, look for flights in the fall and the spring. Avoid the summer in Europe as flights are steep, sites are very crowded with tourists and hotels are more costly.
For any European trip, research multiple airlines and airline consolidators for the best prices. Also look for sales. When one airline commences a sale, the other airlines usually follow quickly. You will generally find cheaper flights at the beginning of the week.
The optimal days of the week to fly to Europe are Tuesday and Wednesday, according to Rick Seaney, CEO of farecompare.com.
