International flights allow one, and often two, pieces of checked luggage per passenger. International luggage allowance is often influenced by whether the flight is intracontinental (within the same continent) or intercontinental (across the ocean or spanning different continents).

In 2026, the baggage allowance for international flights is generally divided into one carry-on "personal" bag and one or two checked suitcases, though this varies by airline and fare class. Most full-service long-haul carriers (like Air India, Delta, or Lufthansa) allow economy passengers two checked bags of 23 kg (50 lbs) each for transoceanic routes. However, a major shift in 2026 has seen many "Basic Economy" international fares move to a "piece-concept" where only one checked bag is included, or none at all. For carry-on luggage, the standard in 2026 is one piece up to 7 kg (15 lbs) plus a small personal item like a laptop bag. Some airlines have become stricter, requiring that your personal item must fit inside your main cabin bag during boarding. Business and First Class passengers usually enjoy a more generous allowance of two checked bags at 32 kg each and two cabin bags. Always verify the "Most Significant Carrier" (MSC) rule if your trip involves multiple airlines, as the baggage policy of the longest flight segment usually dictates the rules for the entire journey.
