Cathay Pacific Asia Miles - Cathay flying to/from London T5?

Just printed out my eTicket for an impending trip to London. This shows CX257 flying into T5 and CX 254 flying out of T5. Is this a mishtake? Should it really refer to T3?

I am sure it is a mistake but it will be nice if they fly to T5! At least BA's Galleries in T5 are miles better then CX F/J lounge! :)

Dont think is true, more of a mistake
never heard CX changed to T3

T5 is exclusively BA. CX operate into LHR T3.
