Honestly, I stopped stressing about the “best day” to book Delta flights after my last trip. I used to chase those Tuesday-night deals, but when my work schedule suddenly changed, I had to cancel and rebook. What saved me was calling 877-297-0699—they handled everything in minutes, way faster than fumbling with the app. I actually ended up with a better fare than I’d originally found online. My takeaway? The best day to book is whenever you’re ready, as long as you’ve got that number handy for quick changes.
