The company announced Monday that the new policy goes into effect on May 4.
The airline had previously required all crew members to wear face coverings while working.
"Wearing a face covering isn't about protecting yourself it's about protecting those around you," said Joanna Geraghty, president and chief operating officer of JetBlue. "This is the new flying etiquette. Onboard, cabin air is well circulated and cleaned through filters every few minutes but this is a shared space where we have to be considerate of others. We are also asking our customers to follow these CDC guidelines in the airport as well."
Customers will be asked to cover their mouth and nose throughout their travels, including during check-in, boarding, while in flight and deplaning.
Delta announced Monday that it is joining American, United and JetBlue airlines in requiring employees to wear face masks or face coverings.
