[DEAL GONE] Europe on sale again: Many U.S. Cities from $477 Roundtrip Now thru Early Dec 2017

UPDATE 1/10/2017 330PM.  This fare sale has expired.  Prices outlined in this post are no longer available.

The last widespread US > Europe fare sale lasted about a week.  This one lasted about 24 hours.  The upshot is, you never know how long a sale will last.  Book now and think later!  Make use of the 24-hour cancelation window.  Get ahold of friends and family members, and work on other arrangements (hotels, rental cars, rides to the airport, etc) AFTER you book.  Nothing bugs me more than hearing someone say, 'I didn't book it because I was waiting for so-and-so to get back to me, so I missed the deal' or 'I couldn't get my brother to commit right away and when I tried to book, the deal was over.'  Don't make this mistake!

This fare sale started yesterday.  Last night I booked a flight for a family of six friends from Detroit to London for $596 round trip during August 2017 -- summer travel to Europe for < $600 each roundtrip is very good.  This morning, I checked again and the same prices were available from Grand Rapids!  So I booked new flights from GRR and will cancel the flights from Detroit since there's always 24 hours to cancel flights (as long as the departure date is at least 7 days away).

This is a very widespread fare sale -- the prices look to be the same for most dates thru the end of the current airline schedules in early December 2017.

• Spring break?  Yes
• Summer?  Yes
• Any other time thru early December 2017?  Yes

Google Flights (google.com/flights) is the easiest way to search, then click thru to book directly with the airlines.

If you are somewhat of a risk taker, try searching on www.momondo.com which shows results from many various online travel agencies.  These OTAs often have cheaper airfares than what are offered directly by the airlines.

Amsterdam, Paris, London, Madrid -- all of these cities are showing availability for $477-$550 range roundtrip on MANY dates.

If you can't find what you are looking for from GRR, try Detroit (DTW) or Chicago (ORD or MDW) for more options.
