As I said last week, USDM avaibility in no way reflects BA/QF/AA/JL tools. The exception is when 3 or more reward seats are available (no shown is on BA website)
Now let's not get completely carried away here.
If there is an argument put forward that simply guessing (or taking a stab at) availability is just as good as using tools (or, in other words, tools
completely misrepresent the US DM availability), I will profusely put forth that is false.
I have found the tools to be fairly reliable for most availability in
oneworld except for noted exceptions. The only recent enigma is CX where JL tends to underreport and the others tend to overreport. I haven't come across a case where JL shows CX availability which you cannot get with US DM, though it is possible to get a CX seat which BA shows yet JL does not. And we well know that it is possible to
not get a CX seat which BA shows (even plenty of), though JL will also show no availability.
AA and BA usually show the same availability for most long haul flights. I tend to find that AA very much underreports BA intra-Europe flight availability, but USDM can book what BA sees just fine. I have had no trouble getting sectors shown on BA whether there were 8 seats remaining or even just 1.
I haven't yet had an instance where AA has shown an option (e.g. on QF) but US DM cannot book it. So I can't confirm
boomy's experience. I'd almost think that's worthy of HUACA - hell, HUACA is always worth a try, especially if you don't have another plan!
Whether there are small quirks in the availability, bottom line is that I haven't experienced so many inconsistencies as to believe that there is no point using the tools any more in planning US DM itineraries.
In addition, I missed your point last week about your experience with the tools; the only thing I commented on was that you were using the wrong tools to find availability which also gave you the wrong price for the award.
Any other tool out there which shows accurate availability for USDM bookings or just need to call every time and hope for the best?
The answer to your first question, I guess, is simply
no.
Let's factor in a few more things here - there is also the agent dimension. From what I can surmise, agents are using a system where their search for availability is not unified. Essentially, they are pretty much using something similar to US's online system except they need to use cue cards to put the right codes to generate the correct availability for each airline. This somewhat explains some of the "instructions" on FT which people have been told to tell agents who are having some issues finding certain airlines' availability (e.g. open a new window, etc.). As someone else also had the same experience as me, with one agent, I had a sector which I found in Business which the agent could not see, so it was held in Economy. Get another agent not too long afterwards, and the seat which as just held in the class of service registered by the first agent was actually in Business!
Assuming that most AAgents will keep their jobs after the merger, when that time comes you can be more confident that AAgents know what they are doing in this regard and have a better idea of classes and destinations, plus award itineraries are priced by the computer, not the agent. Of course, that means you are less likely to be able to fool them or break the rules, an ironic point raised as one of the disadvantages when US DM ceases after the merger.
It is then quite possible that searching for availability on given airlines FF programmes will yield availability which only that programme's members can book. This is especially true if the availability is being displayed of the host airline. It is not common as such, but it can happen. This is one reason purported that searching for CX availability using CX tools (although free as well) was not the best idea.
If it is any consolation (not really), in the old *A arena, there were inconsistencies also noted amongst the popular *A tools used to find availability to feed to US DM agents: Awardtravlr, ANA and UA......
