FAQ

What if the airline uses weight brackets?

Choose the midpoint fee per kilogram or calculate the total fee manually and compare it to this estimate for accuracy.

Additional Information

  • Some airlines charge flat fees for specific weight bands (e.g., 24–32 kg). If so, enter the per-kilogram equivalent.
  • Weigh luggage after adding souvenirs or duty-free purchases—airport scales are usually unforgiving.
