Common questions before you pack
Neither airline is universally more generous; the answer changes by item or by edge. Compare both rows because personal-item and overhead-bag results can differ. Fare and weight rules remain separate from dimensions.
Possibly, but only if every packed edge fits both airlines' current limit and your fares include that item. Use the prefilled comparison, then verify both official sources.
Not necessarily. Inclusion can depend on the fare, route, cabin or add-on even when the dimensions fit. The table shows the published inclusion status; your ticket controls the final allowance.
