So if the OP is slightly delayed and missed DCA-LAX, there's a chance, but not much window for error there either.
On 11/19 currently there's also:
A DCA-DFW-LAX departing DCA at 6:30pm
- and -
A DCA-JFK-LAX departing DCA at 6:51pm [although I wouldn't want to count on the reliability of this connection]
