Studying abroad is the heaviest flight in a student's life. Understanding how airlines calculate luggage helps you carry enough items without spending millions in excess fees.
1. Piece system and weight system
- Package system - common routes to the US, Canada and many traditional carriers: for example 2 packages × 23kg = 46kg, but each package must not exceed 23kg.
- Weight system – for example 30kg or 40kg total, divided into as many bales as possible (each bale is usually ≤ 32kg).
2. How can there be 40–46kg?
- Choose a carrier/segment with a high limit from the beginning.
- Use student discounts (eg Vietnam Airlines' LotuStudents add 1 piece; Singapore Airlines Student can up to 40kg).
- Buy extra luggage before flying - cheaper than buying at the counter.
- Consider upgrading if the difference is less than the baggage fee.
3. Close a smart suitcase
- 28–29 inch suitcases usually fit 158cm; A suitcase that is too large can easily be considered oversized.
- Keep your laptop, documents (passport, visa, CoE/I-20, invitation letter), prescription medications, and power bank in your carry-on.
- Tag your suitcase with a name, take a photo of the suitcase and its contents for easy reporting if lost.
4. Destination country customs
Australia, New Zealand, USA, Canada, Korea, Japan strictly controlled food (meat, eggs, milk, fruit, seeds). Always declare truthfully – false declarations can result in heavy fines and even visa jeopardy.
5. Connecting flights
With the same ticket, baggage is usually transferred directly; Particularly when entering the US/Canada for the first time, you must pick up your luggage at the first airport to clear customs and then send it back.
