I would like to book NYC-FCO RT business class for 3 in July 2014. Right now my anticipated flights are not within the 331 day window, so I am doing a dry run.

It seems that I can never get the same information twice. Specifically, whenever I find an available flight, click out, and return to it a few seconds later, it's gone! For example, this morning I pulled the award calendar for June 2014, which shows six dates at the "Low Price" level. I checked "One Way" for June 11, and I find that there is availability for 3, nonstop for 100,000 miles at 10:15am.

I then tried to pull it up as part of a RT, and now the same flight is available at only the 200,000 mile level.

I go back to check the 10:15 flight again as a one-way, and find it available at the 200,000 mile level.

I go back a few minutes later, and the 10:15 is not available at all!

Likewise, I go back to the award calendar, and what originally showed 6 days at the Low Price level, now shows no Low Price level availability for the month of June.

This is just one example of what has been repeatedly going on during my dry runs. On one such occasion, I called and spoke to a rep after my targeted flight has disappeared, was told that her computer likewise showed that is wasn't available, and that these apparent inconsistencies were really the result of someone booking or reserving the flight within the few seconds I went back to it. I obviously don't buy it. It has happened too many times.

Anybody else having the same problem? (My apologies if this is a known issue. I'm new to this thread and tried to research it, but could only find one similar comment going back to December)
