So I have a FC Amex companion cert under the new T&C and I've spent hours trying to find a flight to either CZM, BON or RTB out of DSM without luck. Actually I found one and waited a couple days and it was gone next time I looked. Is Expert Flyer the only way to search for the "I" and "Z" fare codes I need? And am I right to assume I need the Pro Premium edition to accomplish this? I have a pretty open schedule and have looked for dates in Sept, Oct, Nov and Dec this year and found nothing other than the one I should have nabbed on that one chance I found something. Using the "my dates are flexible" doesn't seem to help at all.
