Whether you pay extra for luggage in 2026 depends entirely on your "Fare Class" and the airline's specific business model. Most Budget/Low-Cost Carriers (like Spirit, Ryanair, or IndiGo) now charge for everything—including overhead carry-on bags. For these airlines, only a small "personal item" that fits under the seat is free. On Full-Service Carriers (like Delta, Emirates, or British Airways), a standard carry-on and a personal item are usually included, but "Basic Economy" tickets often exclude a free checked bag for domestic routes. For long-haul international flights, most "Standard Economy" tickets still include one or two checked bags of 23kg (50lbs). However, in 2026, airlines have become much stricter with weight limits; even if a bag is "included," being just 1kg over can trigger a massive fee of $50 to $100. To avoid surprises, always "pre-book" your luggage online, as paying for a bag at the airport counter is typically 50% to 100% more expensive than doing it during the initial booking process.
