A1 · the table
Fourteen bags, sorted by what boards
The bar under every bag is eighteen frames wide. The number under the bar is how many of them the bag clears with its wheels and handles counted, at the weight listed.
A bag that clears sixteen frames is a bag you can carry on almost any flight out of Suvarnabhumi. A bag that clears none is a bag that travels in the hold and costs extra.
