Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using The Platinum Card® from American Express, you’ll need to book directly with the airline or through the Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.

For many, it’s still far too early to start planning your summer travels. But, putting off your summer travel plans could result in having to pay insanely high prices for flights to and from your preferred destination. This is especially true of flights between the United States and Europe. Luckily, we’re seeing quite a few deals to popular cities in Europe extending into June.

These low fares are available from major US cities to popular cities in Europe such as London and Paris, available in the early spring months into summer. Late March and early April appear to offer the most availability. Still, fares are available starting late February and trail into June. These less than-$400 round-trip fares are currently available through popular Oneworld and Star Alliance carriers including American and United.

If you manage to find a deal that works with your wallet and schedule, make sure you don’t miss out on what your destination has to offer. Check out  Get Your Guide’s list of best activities in popular cities throughout Europe.

To search for these fares, head to Google Flights and enter your origin and destination cities. Scroll through the calendar function to find dates and prices that work for you. Finally, click through to book. Most of these fares are available directly through the airline, however, some fares may only be available through OTAs like Priceline or Expedia.
