A small bag stored under the seat, usually max 40 × 30 × 15 cm. Budget airlines often only include a personal item in the base fare.
How much does a carry-on weigh?
Weight limits vary: 7–10 kg (15–22 lbs) is typical in Europe and Asia; US airlines rarely weigh carry-ons. Check your ticket.
Does a soft or hard bag matter?
Hard cases protect contents but waste space and can exceed strict size limits if wheels/handles protrude. Measure the outermost points.
What is the best size for a checked bag?
A 62–68 linear inch bag (24–28 in) works for most. Larger bags risk exceeding limits and are harder to lift.
