Had a day trip to LAX yesterday. IAD-EWR-LAX at the crack of dawn, with the return originally LAX-BOS-IAD (the latter lie flat the whole way, which is what I prefer in a red eye even if I have to wait an hour in the lounge for a connection the next morning).
On Christmas morning at 6am, I checked in, and .bomb checked me in all the way to BOS, a flight that at that point was ~43 hours away). I have no idea why it wanted to treat it as a IAD-BOS trip with a 12 hour layover in LAX (sure doesn't seem like the way it priced/ticketed).
