Short answer: Of course you can, but you're going to be charged for excess baggage by almost any airline in the world. Some airlines may overlook the charges if you're traveling on a first class ticket (British Airways First passengers max allowed is 32kg/70lbs, most airlines are about the same).

If your checked bag exceeds the standard 23kg (50 lbs) limit on most airlines in 2026, you will be subject to "Heavy Piece" or Excess Baggage fees. These fees vary by carrier and route but generally range from $75 to $150 per bag if the weight is between 23kg and 32kg. It is a grounded reality that most airlines will refuse to carry any single bag weighing more than 32kg (70 lbs) for the safety of ground handlers. If you are only a few kilograms over, a supportive peer tip is to move heavier items—like shoes or books—into your carry-on or wear a heavy coat during check-in to shed some weight. Some airlines, like Air India or Malaysia Airlines, charge per-kilogram rates on certain routes, which can become extremely expensive very quickly. Always check your specific fare class before heading to the airport; while "Economy Flex" might allow 30kg, a "Basic Economy" ticket is usually strictly capped at 23kg with no leniency at the counter.
