Interesting talk about ORD and growth moving forward:
Robert Isom -- President
"We are actually really excited for our future in Chicago on a number of levels. And for one, and I've talked about this probably in lot of forum, removing Chicago to Asia for us has been actually a big benefit to the Chicago hub. A lot of that was not just unprofitable flying in and of itself, it was claiming space off of domestic airplanes and things like that that could have otherwise gone to other customers in the Chicago local market and people connecting from other parts of the business. So that alone has been a big change in Chicago.
And also as we look forward, though our principal competitor there is indeed rolling out the new product, the reality is we still will be able to offer a more first-class seats to the Chicago customer. We absolutely intend to continue doing that. One of the major things that we're excited for, as we go into next year and work through the MAX situation, is that we have a lot more flexibility to do things like bring the A319 in Chicago, which will enable us to kind of up-gauge regional jet markets to vary our capacity more through day and week to create a lot of variability in the schedule that ultimately goes and attracts the key business customers in the Chicago and Greater Midwest area that our principal competitor seems to be targeting. So we very much like our chances out there.
We very much will continue to do that. And even going forward looking longer run as we ourselves continue aggressively replace single-class, 50-seat RJs of two-class airplanes, Chicago will be a place where we'll continue to thrive and be able to produce improving results."
Don Casey -- Senior Vice President of Revenue Management
"This is Don. I'll just add one more data point frame. And we really outperformed the domestic business in the third quarter. They were 12%, and our best-performing hub for unit revenue was Chicago."
Vasu Raja -- Senior Vice President of Network Strategy
"To your first question about Envoy growth, which I think in part you meant Envoy, and maybe larger you meant kind of regional versus mainline. I'll speak to both. Our growth this past year has been heavily driven by the regional operation.
Next year, it will be more heavily driven by our mainline operation. Our growth in Charlotte especially is less about growing our regional jets, it's about, one, improving the connectivity of the hub, making more O&D market and then very critically having more seat availability. So you'll see us do things like bring the 737, then in a larger degree turn more regional jets in the mainline. We endeavor to doing the same thing in DFW as well."
