My point is that a ONE trip usually begins with making the bookings, followed days to months later with the purchase of a ticket, so you should have been given bookings the day you first presented your travel request to BA/MRU.

Unfortunately, BA has their own anti-ONE rules, and their distant outpost in Mauritius seems more than anxious to follow them. In particular, BA seems anxious to restrict ONE traffic ex-MRU because of the low prices. I have no idea who other than BA set those prices, but they're obviously doing everything they can to keep travelers from using them. The oft-discussed topic that MRU-LHR seats appear in the CRS's of the world, but simply cannot be booked by the MRU outstation is a case in point.

Many agencies around the world have the right to book seats on BA aircraft on your behalf, and designate them to be held for a length of time before money changes hands. Normally, one can include such an existing booking into an ONE trip simply by giving the person doing the ticketing the PNR number.

My first step would be to use Expert Flyer or a similar tool to find availability for flights you can accept for the beginning of your trip.

Second, I would find a BA office that would lend a sympathetic ear to your difficulties booking out of MRU, and who would make that booking for you. Assure them that you just need them to grab the seats, because the folks in MRU, wonderful though they might be, are having some sort of difficulty doing so, and you would like to know there will be space for you when they sort it out. Make it clear that you're not asking the office for anything more than the booking, and ticketing will of course be done in Mautitius.

Some BA offices (e.g. North America) have specifically been told to refuse wannabe travelers such a favor. Others in Europe have specifically been mentioned as going much farther in being helpful. Hopefully the community here will PM you with their favorites.

Third, I would make sure my ticketing request to BA/MRU was totally uncontroversial. It will only cost USD125 extra to have some less restrictive airline re-issue it the way you really want it, once you leave BA's proprietary turf. My request to IBL Travel was nothing more than MRU-LHR-LAX-HKG-JNB, although I certainly planned to ultimately fly 20 segments.

The only problem I see is that MRU will fuss about not being able to price your ticket without having that first segment defined. I suggest you tell them to wait-list you for first class and confirm you in coach for the purposes of issuing. Make sure they show the segment ticketed in A class for "when the wait-list clears" - they sometimes make the ticket match the res, not the fare class.

PM if I can further confuse the situation ... I had that AMS contact once, I think, and if so can dig it out of my own mail. Meanwhile, it would be nice if the OW experts would throw water or support on my suggestions on how to go forward.

[BTW I personally would be quite anxious to get this done in the next few days - the suggestion "by Nov. 30" may have been more of a warning. However OW sets fares, MRU sticks out as too much the bargain, probably highlighted by all the traffic from there engendered by this very forum - the other edge of the "we're so helpful to wannabe OW travelers" sword.]
