Louisiana Aircraft Inc., a fixed-base operator on the south side of the airport has been purchased by a real estate developer. The developer has plans to build more hangar space and has purchased the old Capitol Jet Center / LuxJet FBO located on the east side of the airport. Future plans include a ramp and hangars on the north side of the airfield. The increase in hangar space is most noticeable during the College Football season. This future expansion is causing the Army National Guard armory of the 769th Combat Engineer Battalion to relocate to the other side of Baton Rouge.

On June 24, 2010, US Airways recommenced operations to Charlotte from BTR.

In March 2012, a project to expand the rotunda area of the terminal began. The purpose of the project is to relieve the traffic jams inside the terminal caused by passengers going through security screening or departing the airport in the same general area that the walkway from the parking garage and waiting area are located. The renovation project is expected to be completed sometime in August 2013.

In September 2013, Baton Rouge Metro Airport announced the August passenger volume hit a 5 year high. The Baton Rouge Metropolitan Airport experienced its best August passenger count in five years. A total of 66,860 passengers passed through the airport for the month. The August departing passengers (enplanements) were up 11% at 33,465. Arriving passengers (deplanements) were up 7.08% at 33,395. Delta maintained the top August market share at 42%, followed by United at 25%, American Eagle at 24% and US Airways at 9%. Delta had the biggest passenger increase among the BTR airlines at +13.03% in enplanements and +10.15% in deplanements.

Delta has also begun scheduling larger, dual-class aircraft into BTR, including CRJ 700/900, MD-88, Boeing 717, and Airbus A319 aircraft. All four aircraft types have both first and economy class seating.

Since 2016, United has begun scheduling larger ERJ-175 aircraft which include first, economy plus, and coach class seating.

In September 2013, Baton Rouge Metro Airport announced Delta's "Red Coat" Service has been implemented at the check in terminal to assist customers.

The expanded rotunda opened in October 2013 and the TSA checkpoint has been re-located to the new area, providing more room and allowing an additional line to be added when necessary. The original rotunda now serves as a spacious arrival court where un-ticketed guests can wait on arriving passengers. Construction of new restrooms and vending in the arrival court are complete. New restrooms on Concourse A are also open, including a family restroom and lactation room. The new rotunda provides an airy space for passengers that includes a floor-to-ceiling glass wall with a great view of the airfield and runways. New seating in the rotunda provides an outlet at each seat, and a charging station has been added at the beginning on Concourse A. The renovated food court now includes PJ's Coffee and WOW Cafe: American Grill and Wingery. The airport sports lounge has also been expanded and renovated. Other airport amenities include free Wi-Fi, a business center, chapel, and a children's playroom.

In January 2016, it was announced the airport is seeking to open a hotel that would connect to the BTR terminal. Baton Rouge Metro Airport is looking to add a hotel and restaurant to its north Baton Rouge terminal in hopes of growing airport revenue and adding convenience for travelers.

The airport's board of commissioners accepted a request for proposals from Holiday Inn representatives to explore building a 147-room hotel with a Mike Anderson's Seafood. Holiday Inn representatives are still studying the market, but they are expected to make a determination in the next couple of months on whether they can build the hotel.
