While my favorite miles-for-flowers offer is FTD’s ongoing 30 United miles per dollar spent, it’s worth noting that FTD is also offering 25 Delta miles per dollar spent.
The Delta offer is a Mother’s Day promotion. The e-mail from Delta announcing the offer says it will expire May 15, but the webpage itself doesn’t seem to mention a deadline — and if experience is any guide, the offer may still work past the stated deadline.
