As Michele and Steven Burt's French bulldog, Darcy, began to struggle to breathe on a recent JetBlue flight from Florida to Worcester, crew members on board the plane quickly and calmly came to rescue.

It just so happened that one of the crew members also has a French bulldog.

The Burts are now crediting the crew members, Renaud Fenster and Diane Asher, for saving Darcy's life.

The couple from Westminster, Massachusetts was on a JetBlue flight headed to Worcester on Thursday with their three dogs.

Darcy, who is 3, started pushing her head against the mesh part of her carrier, Michele wrote in a letter she sent to JetBlue. She provided the letter to MassLive.

Michele saw Darcy wasn't getting better and loosened the zipper on her carry-on, so the pooch could poke her face out.

"I noticed that her tongue was blue, and I am aware that is a sign of insufficient oxygen (Hypoxia), so I pulled her out from under the seat and placed her on my lap to cool down and help her relax as she was panicking and breathing frantically," Michele wrote.

A flight attendant politely told Michele that Darcy had to remain under the seat in her carrier because of regulations. Michele told the crew member Darcy needed help.

Fenster and Asher brought ice bags for Darcy, hoping to cool her down. But Darcy continued to pant heavily.

"Renaud, who explained that he also had a French Bulldog 'Penelope' brought a small oxygen tank with a mask attached and offered it saying, 'Maybe this will help'. I placed the mask over her face, and within a few minutes she became alert and after a short time she didn't want the mask," Michele wrote. "I believe Renaud and Diane saved a life, some may reduce the value of the life because Darcy is a canine, I do not."

Darcy is a family member, Michele wrote. The goodness and kindness of the crew showed the best of humanity, she told MassLive.

JetBlue responded to Michele's letter stating they were happy to hear the crew members went "above and beyond" in helping Darcy.

"Our mission is to inspire humanity, and we're very proud of those outstanding crewmembers who consistently demonstrate a passion for excellent customer service," JetBlue wrote. "We will forward your message to our Leadership Team so that Renaud and Diane will receive recognition for the kind help."

Darcy is now home and the Burts will check with a veterinarian before taking her on a flight.

"She's home, happy and chasing squirrels," Michele said. "She's doing great."
