Hey FT, trying to book Delta flights through the Air France website to take advantage of a recent AmEx Offer ($1,000 spend for 20,000 Membership Rewards). I'm planning on booking a few Delta flights, the first of which is BOS-MCO, probably roundtrip, somewhere in the week of February 28th. There's plenty of flights on the Delta site, but every single time I try to find them on the Air France site, I get "No flights available on the selected date. Please call us at the number listed at the bottom of this page. (3203)"

To be fair, I haven't tried calling yet (AmEx Offer won't work for flights booked via phone). I've tried different dates (all with Delta availability shown on Delta.com), different classes, etc. Not sure what else to do, any thoughts?

Doesn't seem to be any relevant/current information on FT either
