Yes i have had some good and some totally painful experiences now....
Some agents (well most) are relatively great and you can get straight down to it, some are just a bit clueless, and when their supervisor then is also clueless it becomes a chore (like the other night when i was trying to book a redemption and i was told that my flight that arrived into BKK at 10.40pm or so and then the next flight to FRA that departed at 5 minutes past midnight would be counted as a stopover as it was the next day... Then also it being a fairly straight forward OZ-via Asia-EUR-US-via Asia-OZ booking would cost me 300,000 miles... then even though pretty straight forward and direct i was 1000 miles over the MPM...) After about 2 hours of circular nonsense i gave up and plan to call again tonight or tomorrow... this should be getting close to about 10 hours i have now spent on a couple of attempts to get this one done, although i have had started over a couple of times admittedly... Sorry if that sounds a bit entitled as well....
There was the night i spent about 3 hours on the phone and if it there wasn't one probelm, there was another, we thought we had sorted it out and off to the rate desk, then some entirely new issue came up, solve that back to the rate desk and then something else out of left field... I did ask at one point if US Air just didn't want me to fly with them... But because the deal can be so good and i have lots of points i will keep perservering...
