If you fly from Meridian to Atlanta in the next couple of days, you'll be among the first to use the new Delta ASA Jet Service.
Passengers who have flown in the older model prop planes are glad to see the change, mainly because the jets are more comfortable.
"They'll feel more comfortable and be a big improvement," said Latara Ingraham, a passenger on her way to Atlanta.
The pilots and crews have been training on simulators to be ready for the changeover Sunday morning.
