United Airlines is cancelling 737 Max flights through early July

United Airlines says it is cancelling flights through "early July" because of the Boeing 737 Max grounding. The airline joins other US carriers — American and Southwest — that have canceled 737 Max flights to avoid disruption as people book flights for the upcoming travel season. "We've used spare aircraft and other creative solutions to help our customers...get where they are going," a United spokesman said Monday. "But, it's harder to make those changes at the peak of the busy summer travel season." United said the initial decision to take the planes out of service affected "roughly 40 flights a day" at the time. The company doesn't fly any Max 8 jets, the type of plane that was involved in both of the fatal incidents. But it does have 14 Max 9s, which are a slightly longer version of the Max 8. <br/>
