I can see BA shutting down dupe's like CAI,DME,RUH ..etc The (14 slots)

But will they close routes where they have OW carrier flying to LHR ! For example RJ is OW,why BA should send it's metal to AMM while they can sell on RJ they may reach an agreement to hard block seats! I know RJ arrival time to LHR is very bad for connecting passengers,esp cross Atlantic, but isn't cheaper for BA not to send an aircraft to AMM !!
On the other hand EJ is also flying from AMM to Gatwick will this be another reason for BA to fear flying to Jordan and leave the route for RJ and EJ !? I hope not,Ive been waiting for BA to get back to Amman since Bmed were sold.
Wondering !!
