Hey awardtrail readers, dreaming of Gaudi and tapas? United and its partner airlines (think Air Canada, Lufthansa, etc.) are offering some sweet deals to Barcelona for as low as $550 in economy! This is a pretty standard economy fare, so it's not a screaming steal, but definitely worth a look if you're planning a trip and haven't booked flights yet. Why should you care? Well, Barcelona is an amazing city, and saving a few bucks on flights means more euros for sangria and delicious paella! Keep an eye on these fares, especially if you have some flexibility in your travel dates. Remember, these are basic economy fares, so baggage fees and seat selection might cost extra. Time to start planning that Mediterranean escape!
