Follow these strategies to avoid paying top dollar to fly across the Atlantic. By Cameron Huddleston, Former Online Editor April 18, 2014 Thinking about taking a European vacation this summer? If so, you won’t be doing your wallet any favors by heading overseas during the peak travel season. That’s right, summer is the most expensive time to go to Europe because so many tourists head there at that time.

Even Europen vacations in early fall and late spring are more affordable than in the summer. But don’t despair. If a summer vacation to Europe is what works best for your schedule, there are ways to avoid paying an exorbitant amount to get across the Atlantic. Book your flight as early as possible. Ideally, you should book a flight to Europe 11 months before your trip to get the lowest fare, says Jeff Klee, CEO of CheapAir.com, which monitored fares for more than 4 million flights in 2013 to determine the best time to book flights. But that doesn’t mean you’ll pay top dollar for a summer flight to Europe if you book now. Just make sure you purchase tickets at least six weeks before your departure because fares will dramatically increase after that point, Klee says. If there are still more than six weeks before you plan to travel, Banas recommends signing up for fare alerts from Kayak.com or Airfarewatchdog.com to be notified when the price drops on the flight you want to take. Although prices typically rise as the departure date for a flight nears, airlines occasionally release some seats back at the lowest fare level, Klee says. Also sign up to receive e-mails from the airlines about fare sales and follow them on Twitter, where some airlines announce limited-time sales, says George Hobica, founder of Airfarewatchdog.com. If you see a good price on a flight you want to take, don’t hesitate to purchase tickets. Advertisement Fly on a Tuesday or Wednesday. These days tend to be the cheapest days to fly to Europe; whereas Friday, Saturday and Sunday are the most expensive, Klee says. Check several travel date combinations. The price of flights also can vary significantly throughout the month. So if you don’t have to travel during a specific week, use the flexible date option at Kayak.com to find the dates with the lowest fares. Consider lesser-known airlines. Norwegian Air Shuttle has had a sale on flights to Europe from a few U.S. cities, Hobica says. Many of the low fares have been snapped up, but you might be able to score one if you act quickly. Other lower-cost carriers include German airline Condor, Icelandair, Turkish Airlines and XL Airways France. Choose cheaper hubs. If you don’t have your heart set on a particular European city, choose one that’s cheaper to fly to. Klee says that Dublin, Ireland, is the cheapest European city to fly into, on average, this year. Flights to Milan are at least $200 less than flights to Rome. And flights to Brussels, Belgium, are cheaper than flights to other Central European cities, Klee says. Copenhagen, Denmark, and Oslo, Norway, are the least expensive cities to fly into in Northern Europe, Hobica says. The map at Google Flights shows the average price of flights from a departure city of your choosing to cities around the world to help you pinpoint the least expensive European cities to which you can fly.

Don’t neglect business class. Airlines typically have sales on business-class seats on summer European flights, Hobica says. Sometimes business-class fares drop below the price of economy tickets, he says. Typically, though, the prices on these discounted seats still are a few hundred dollars more than economy fares. But if you’re going to be taken to the cleaners with a pricey flight to Europe, he says, you should do so in comfort by paying a little more for the better seat. Look under fare specials on airlines’ sites, sign up for their e-mail alerts and check their Twitter feeds for these deals.
