The plane was forced to make an emergency landing as the 15-month-old toddler started to turn purple.
Thankfully, one of the passengers on board the flight was a former army medic who now teaches CPR for a living.
Garrett Goodwin performed chest compressions and gave the child the kiss of life, until he started to breathe unaided.
"You're scared, but your training kicks in," Garrett told FOX 10. "I was at the right place at the right time with the right experienced training and I hope anybody with any amount of training would have done that."
One passenger who witnessed the incident said:
When we heard the baby cry it was a teary moment for everybody.
It is not yet known what caused the toddler to stop breathing, but he is said to be doing well.
The rest of the relieved passengers were then able to continue their journey and arrived in Arizona just an hour late.
