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…..

I was told by the security screeners in OAK that Uber does not come to the ramp. I've never ops checked that, but Lyft worked just fine.

My experience is that Uber treats the airport like one giant block on the map. While Lyft actually cuts out the non-terminal/fenced parts on the map for pick up. At least that is the case in DTW. Uber will always just place the pin at the terminal and there is no way to put it at the ramp. While Lyft will let me place it right at the ramp.
