        "longDescription": "Will my carry-on fit? Is my backpack a personal item? How much is a checked bag? Packfits answers with each airline's own published rules, not guesses.\n\nAirline bag rules: carry-on, personal item and checked bag limits in inches and centimeters, weight limits, typical bag fees and the fare caveats that catch travelers out, such as Basic Economy. Every rule links to the airline's official page and shows the date it was last checked.\n\nBag fit check: give your bag's outside size and Packfits tells you whether it fits, is just over the limit, or is too big. Bags can be turned to fit the sizer and soft-sided bags get a little leeway, the same way the packfits.com checker works.\n\nCompare airlines: ask \"what is the standard carry-on size?\" and get every covered airline's limit from smallest to largest, plus the most common size, or learn which airlines your bag fits.\n\nBags that fit: ask for a carry-on or personal item that fits an airline, or have a bag that does not, and Packfits lists bags from its catalog that fit, with links to their Amazon product pages.\n\nTheme parks: official rules for bag size, prohibited items, outside food and drink, lockers and strollers at 12 parks, including Disney World, Disneyland, Universal Orlando, Six Flags and Cedar Point.\n\nCruise lines: prohibited items, luggage, dress code and what the stateroom provides on 10 lines, including Royal Caribbean, Carnival, Norwegian, Disney Cruise Line and Princess.\n\nAirlines covered: Delta, United, American, Southwest, Alaska, JetBlue, Frontier, Allegiant, Ryanair and Lufthansa.\n\nNo account or sign-in. Packfits only reads its own published data and never asks for personal information. Packfits earns a commission from qualifying Amazon purchases.",
