Skiplagged is a service that allows travelers to book flights with layovers, often resulting in lower prices than booking direct flights. When booking through Skiplagged, it is still possible to check a bag, depending on the airline's policies. But, it is important to note that Skiplagged recommends traveling with carry-on luggage to avoid potential issues with checked bags during layovers. Additionally, it is vital to carefully review the airline's baggage policies before booking a flight through Skiplagged to ensure you know of any potential fees or restrictions.
