United has been having some great fares to Europe this week. Fly from several US cities to Amsterdam, Paris, Rome, Madrid, Barcelona, London, and possibly more cities, with round-trip fares in the mid-$400s to $500s range. Fares dip as low as $397 round-trip.

This is unadvertised and may not last very long. Book quickly if something catches your eye. Most third party booking sites have a 24-hour free cancellation policy so you'll have a day to figure out the details. You may find lower fares on low-cost carriers for certain routes, but these United fares will include full service and one free checked bag.

Travel is available in May/June and again with departures in August/September. Return travel must occur before June 21 or again starting in late August. A 28-day advance purchase and a 7-night minimum stay is required. Some flights may be operated by Star Alliance partner airlines. Click on the links below for full details on each route.
