I want to take Metro+ on a plane – is it approved as cabin luggage?

The Metro+ will fit in most overhead bins. To be officially “cabin approved”, luggage needs to be able to fit underneath the airplane seat, which the Metro+ will not. In most cases, you’ll be able to bring the Metro+ on a plane, but depending on plane size and amount of overhead space available at the time of boarding, like most roll-along luggage, you may be asked to gate-check it by airline staff.
