Hey awardtrail readers, dreamin' of Hawaiian sunsets? Listen up! There's a sweet deal floating around for flights to Kauai (LIH) for under $400 roundtrip on Delta. Yes, you read that right! This isn't some bare-bones, ultra-restrictive fare either. We're talking about Delta's regular economy, which *includes* advance seat assignment and a normal-sized carry-on. That means no surprise baggage fees or scrambling for a decent seat. If Kauai has been on your bucket list, or if you're looking to score a cheap inter-island flight, this could be your ticket. Get booking!
