Last year, Boeing upgraded the cabin of its Boeing 737 with new features such as LED lighting, bigger overhead bins and new ceiling panels.
It says the changes are cost-effective.
For instance, the new lights in the cabin are longer lasting and energy efficient, with an estimated 40,000 hours life between replacements.
This compares with 4,000 hours for the previous standard of lights.
Jet will be the first Indian air carrier to get Boeing 737s with these features.
Air India Express and SpiceJet also operate Boeing 737s.
