Thay are a small office and very busy thanks to people like me re-routing concurrent AONE's from them and yes you do have to wait a but but for the difference in price I feel its well worth it. I'm on my third ticket with them and also use then to change other BA tickets for me as they are more efficient than BA elsewhere as I am a QFF hence have to hold for about 10mins to speak to anyone from BA

Where is the second cheapest place for Aone's at the moment?

For anyone calling into MRU for their next ticket not wanting a direct turnaround I have a taxi driver who picks me up. gets me locals rates at good hotels, picks up my tickets...he's the MRU concierge and very reasonable.
