I’m in same situation and am experimenting. I bought a FC ticket for May and used Company credit card. It showed up on expense report website and I was able to ignore it until another charge showed up that I had to reconcile for Feb report. That forced me to address it. I put in the May travel date and flight number and tried to assign it to a April trip (not within 3 days). It accepted it but assigned it a tag of “unauthorized “. I figure when I get my May schedule I’ll “remove” the credit card charge form May report and when it shows back up on the credit card page I’ll redo the info and assign it to a qualifying May trip.
Anyone else try this route? Will update as month progresses…..
