Delta Airlines will begin a daily flight to Seattle beginning August 1st, 2014, due to their recent announcement that they are starting to consider Seattle as a focus city/hub with all of the new flights they are operating from Seattle. Currently, Alaska is the only airline with flights to Seattle from KIA. Delta will operate the daily service using either B737 or A319 aircraft, and the flight will most likely operate from one of their gates at Terminal D, gate D3 or D4. Southwest is also considering beginning service to Seattle, but if they did it wouldn't be until the end of the year when they receive extra gates from AirTran due to the merger.
AirTran Airways has announced that, due to the merger between Southwest and AirTran that is set to be complete at the end of this year, they will begin cutting down their service from KIA beginning as soon as the end of this month. They will end all flights to Milwaukee and Orlando on June 30, 2014. Their flights to Baltimore and Atlanta won't end until December 28, 2014, which is the last day of AirTran operations before the merger is finished. However, Southwest already operates flights from KIA to Milwaukee, Orlando, and Baltimore, so there will still be service to those cities. Southwest is also set to begin service to Atlanta on July 1, 2014, well before AirTran ends their flights to Atlanta. Southwest will not take over AirTran's gates (B3 & B4) until December 29, 2014, the day after AirTran's last flights from KIA. Once the merger is complete, Southwest will have control of more gates at the airport than any other airline that serves KIA (except for Delta). They will have four gates at Terminal B (B3, B4, B8, & B9) along with two gates at Terminal D (D5 & D6). Southwest and Delta will then both have six gates at KIA. Southwest hasn't yet decided what they will do with the two extra gate acquisitions, but they will most likely add more flights to some of their focus cities such as Chicago-Midway and Phoenix.
United, Virgin America, and Frontier have announced upcoming service changes from KIA. United will reduce service to Cleveland by reducing the weekly number of flights by 6, from 20 to 14. They will keep the 9:45am and 1:00pm daily departures but end the 5:15pm flight that arrives just after midnight in Cleveland. This flight will end later this month. Frontier is ending both of their flights to Milwaukee; they have not been profitable for them in many months. However, Frontier will begin new service to Cleveland to make up for United decreasing service there. Frontier's service changes will also take effect later this month. Virgin America has also announced that they will begin service to Dallas-Love Field starting this fall. There will be one daily flight that will compete with Southwest's already existing twice daily service to Love Field.
