Affordable Round Trip Flights

Find me affordable round-trip flights for a 5-7 day trip in [Month or date range] from [Your Departure City] to cities that are known for being interesting and budget-friendly. I’m flexible on exact travel dates and open to nearby airports. Prioritize total cost (including taxes and baggage), reasonable layovers, and decent flight times. Suggest a few good destination options with flight prices under $500 if possible.
