Why go now
$402 per person round trip, nonstop, is $193 below the highest fare we saw for these dates, which reached $595. That's 32% less across the 12 offers we checked, and $402 is also the lowest fare in our recent checks on this route. Flights for two come to $804. Add the Horseshoe at $496 and a $520 spending budget, and the whole weekend comes to $1,820 for two. Late October is a comfortable time for the desert, with highs of 69–77°F, lows of 61–65°F and no more than a 6% chance of rain on any day. The flight leaves at 1:30 PM on Friday and lands at 3:15 PM local time, so you're in town for dinner and a show that first night. Prices were all-in when we checked and can change.
The kind of trip this is
This is a city-and-nightlife weekend with a little desert on the side. It suits couples or a small group of friends who want big dinners, a show, some time at the tables and a slow pool or canyon morning before flying home. The pace is up to you: go hard Friday and Saturday night, or keep it easy, with two nights and a short, nonstop flight on each end.
