As you've probably heard, DOJ has settled with US & AA to permit a merger, pending divestiture of assets at certain airports:
44 slot pairs (10% of DCA's market share) are up for grabs between at least two carriers.
The usual stable of growing LCCs, like WN, B6, & NK,
plus DL, have all expressed interest. Which airlines do you think have a compelling case?
US/AA have stated that the cuts will come from RJ destinations, which will result in a cut of almost 40% in RJ flying. DCA-RDU and DCA-BNA are certain to see frequencies cut, as those are the two routes both fly RJs to. What other destinations could see less, or more, service?
