EVIDENCE & METHODOpen the full buying logic
Why 66–68 cm is the default check-in starting point
A medium case usually balances packing room, lifting, car-boot fit, home storage and the risk of exceeding an airline weight allowance. It is not automatically correct, but it is a more defensible default than buying a 77 cm case for an ordinary trip.
When a 77 cm check-in case makes sense
Use a large case for a long trip, bulky clothing, deliberate shared packing or a journey with ground transport that can handle it. The extra shell volume does not increase the airline's weight allowance and can encourage avoidable overpacking.

Questions buyers ask
What size check-in luggage is best for most travellers?
A 66–68 cm medium case is the most versatile starting point for many trips. Use a 77 cm case only when the packing requirement and transport plan justify it.
Is 77 cm luggage suitable for a 23 kg allowance?
It can be, but the large volume makes exceeding 23 kg easier. Include the case's empty weight and leave room for return-trip purchases.
Do I need a TSA lock for domestic travel?
Not necessarily. A TSA lock is more relevant to some international journeys; size, weight, shell, wheels, handle, seller and returns remain material purchase checks.
