What Is the Biggest Suitcase You Can Fly With?

The 158 cm rule

Most airlines: 158 cm (sum of dimensions). A suitcase of 80×55×28 = 163, already over!

What happens if you go over?

An extra fee. In extreme cases, they will refuse it. Measure in advance, including the wheels.

The recommendation

A 75 cm suitcase (L) is the safe size. Choose a suitcase that meets the standard.
