Amazingly for the first time we have received an OPUP from WTP to CW on the leg of our flight departing LHR. Even better they have given us increased Avios and tier points which I didn't expect. However, three of us start the journey in Manchester and won't have time to use the Lounges in T5. Will we be able to access the lounge (is there a lounge at Manchester T3 ?) as the Manchester portion of the flight is just normal economy and Silvers can't take in more than one guest?

Also do domestic connections count towards qualifying flights? Or is the qualifying flight for example MAN-SIN or is it MAN-LHR is one and LHR-SIN is two?

Thanks in advance
