    Cabin vs checked baggage, battery capacity and airline approvals.

  3. 03

    Customs requirements

    Duty-free allowances, declaration forms and what happens at the counter.

CarryRules summarizes official customs, aviation and government sources. It is an independent reference, not a government authority.
