Giving passengers five more minutes to board cut Delta's delays

the gist

Five extra minutes of boarding time cut flight delays. On 2 June 2022 Delta Air Lines lengthened the scheduled boarding time for all domestic narrow-body flights from 35 to 40 minutes by taking time from other gate tasks such as deplaning, cleaning, refueling and baggage handling. The same day it became the first US airline to pay flight attendants for boarding, at 50 percent of their regular hourly rate. A study in Production and Operations Management found flights left about 1.5 minutes sooner, and the chance of leaving on time rose by 32 percent.

so what

Small changes to schedule design can reduce delays that ripple through an airline network, a bigger effect than the minutes suggest.

fun fact

A single late departure can cascade, since the same aircraft flies several legs a day.
