Delta has round-trip flights from Denver (DEN) to Barcelona (BCN) for $443-$457 with a connection. Flights September to March. Departures on Monday, Tuesday, Wednesday, and Sunday.

A Carry-on bag and also a personal item is allowed for free on Delta. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.

If you travel on Delta often, consider getting their credit card. Most of their cards allow for a free checked bag perk and a 15% discount on points redemptions.

There is currently a limited time offer for Delta’s co-branded credit card with a higher than normal welcome offer! (the card offer ends 04/02/2025) Visit our Delta credit card landing page for the current sign-up offer and more details (link).

You can usually save more money by booking your flight+hotel together as a package instead of separately.

Do a search on Tripadvisor and GetYourGuide to find guides, tours, attractions, and cool things to do. I use both of those sites to help me plan my own day-to-day itinerary while on vacation.

We post new flight deals often! You can check out our other deals by returning to the Front Page of our website: escape.flights (linked).

Here are some other offers that we think are worth mentioning. List updated 06/13/2025.

We now track coupon codes, discount codes, gift card discounts, and credit card offers that have a better value than their historical averages.

  • Tips: The Chase Sapphire Preferred® Card allows for 1-to-1 point transfers to several airline loyalty programs. Booking with points is a good alternative to paying with cash when the price of airfare is high. Here is the current list of Chase Sapphire transfer partners: United, Southwest, jetBlue, British Airways, Iberia, Singapore Airlines, Emirates, Air France, KLM, Virgin Atlantic, Aer Lingus, and Air Canada.
  • Tips: Use Tripadvisor to create a Hotel “short list”. First, plug in your dates and destination. Then select “Sort by Traveler Ranked”. Finally, select the “Traveler Ranking” filter to show “only 4* and up”. Use this resulting “short list” of hotels to find the cheapest one with a high ranking.
  • Tips: Hotel rates for Weekend dates are usually higher than the rates for Sunday through Thursday. Tripadvisor has a color-coded date calendar, red when the average hotel price for that day is more expensive, green for less expensive. You can use this to get an overview of what dates in the month are at a discount.
  • Tips: Different booking websites will often have differing routes, prices, and availability. Before you finalize your purchase, do a quick check on BookingBuddy, Skyscanner, and Kayak to see if any other site or airline is offering a better deal.
