The Globe on Dec. 18 had a chance to accompany a JetBlue crew as it made multiple trips on a run between Boston’s Logan Airport and Newark Liberty International Airport in Newark, N.J. Short turnaround times mean crews are always on the go, even when they’re on the ground.

Here, JetBlue flight attendant Tracy Christoph climbed stairs at Logan Airport. She had left a crew area and was heading to a gate for her Newark-bound flight.
