I agree with most of the foregoing comments. I could never understand why AA wanted the route which would not only dilute its own HRW traffic but would also upset its ONEWORLD partner BA.
CO always seemed to me, the perfect operator for the route, not having access to HRW and having its huge hub operation at EWR, let's hope all is not lost.
I have been keeping an eye on the seatplans, which was made difficult by a large block being made unavailable for booking but I can say from my latest check of visible sales showed that the 2nd May flight had 18 bookings outward and the busiest day was 27th May with 82 at the last count. There was a good spread of double figure bookings throughout.
