Travelers pick flights by price and schedule. But if you want to get there as planned, it’s worth paying attention to which type of plane you choose.

A data dive shows different types of planes within airline fleets have varying records for on-time arrivals and cancellations. At some carriers, older planes have more delays. Sometimes it’s brand-new planes that suffer more glitches. More important than age: How each airline flies and fixes particular planes impacts whether you’ll be late or stranded.
