Airlines have become increasingly strict about carry-on baggage sizes. Gate agents now frequently check bags using sizing bins ("sizers") before boarding. If your bag doesn't fit easily into the sizer, you will likely have to check it and pay a fee.
Different aircraft types (like regional jets vs. wide-body planes) also have different overhead bin sizes. While an airline might have a general policy, specific flights might have stricter limits. Our tool provides the general policy limits, which is the best baseline for planning your packing.
