Common Mistakes to Avoid
⚠️
Not knowing your airline's specific limits
United, Delta, American: 50 lbs. International business/first class: often 70 lbs. Spirit/Frontier: lower limits and higher fees. Always check airline-specific rules.
⚠️
Packing at home without weighing
A luggage scale ($10-15) is essential. Scale at home vs scale at the airport (often inaccurate) — always weigh before you go.
