But then I discovered that if I depart from BOS and return to FLL, I could get the fare to drop to $4,050. I'm pretty sure I searched that on AA's website, but now I can only get that fare if I search it on the app. On the website it's now $5,601. Right now, as I type this, I'm coming up with the exact same flights -- BOS-JFK-DOH-NB0-DOH-JFK-CLT-FLL -- to price out in J at $4,050 on the app and $5,601 on the website.
