Hey awardtrail readers, dreaming of sipping port wine in Portugal? Well, good news! There's a decent deal popping up for flights to Porto (OPO) from around $664. Keep in mind that the exact price can wiggle a bit depending on the specific route you choose. What makes this deal worthwhile? This fare actually includes advance seat selection and allows for a regular-sized carry-on. So, no hidden fees to worry about before you even get there! Why does this matter to you? If Porto has been on your list, or you’re just looking for an affordable European adventure, this is your chance! Being able to select your seat ahead of time makes for a more comfortable journey. Always check the fine print before booking, but these fares appear to offer a bit more flexibility than the rock-bottom basic economy fares we often see. Happy travels!
