THIS WEEK'S FARE BLOCK

Eight cubes the desk likes this week

Editorial picks updated daily. The catalog desk reads partner feeds every morning and pulls eight cubes where the public fare is meaningfully below the trailing 14-day average for that route. Each pick is accompanied by a two-paragraph rationale on why the fare is interesting and what to watch out for at the partner checkout.

Las Vegas under $90 is the floor of the entire western catalog. Ultra-low-cost operators set the price and the larger network operators match within hours; book on Tuesdays for the best chance of catching the floor before it lifts.

Companion-pass loyalty programs on point-to-point operators effectively halve this fare, making PHX-LAS one of the cheapest round-trips in the country.

PHX-DEN is the most-competed Mountain-West route in our catalog. Three operator categories run multiple frequencies daily, keeping fares in the $120-$150 corridor outside of ski season.

Ultra-low-cost bag fees can flip the all-in math; if you check a bag, the bundled-baggage point-to-point fare often beats the headline ULCC price on total cost.

Multiple Pacific-coast operators run frequent service on PHX-SFO and treat it as a meaningful spoke from a SFO focus city. The fare is competitive year-round.

SFO fog delays peak in May, June, and July mornings; book afternoon departures if a tight connection follows.

PHX-LAX under $80 is the cheapest network-operator route in the catalog. Multiple operators run shuttle-style frequency; the route is rarely a problem.

For a same-day Los Angeles meeting, a 6 AM out and 9 PM back is feasible on every carrier.

Pacific-coast operator service on PHX-SEA runs multiple daily flights and treats Phoenix as a meaningful Pacific Northwest connection point.

Premium-economy buckets on the route include free alcohol and are sold as a separate fare bundle at a modest upcharge; worth it on the 3.5-hour leg.

PHX-PDX is the second-cheapest Pacific Northwest route after Seattle, with multiple operators splitting the schedule.

Portland's MAX light rail makes airport-to-downtown trivial; budget 40 minutes.

PHX-SAN is the second-shortest mainline route in the catalog after Tucson. Multiple operators serve it.

San Diego's airport sits inside the city; no rental car is needed for downtown stays.

PHX-SLC connects to a major western network hub. The route is rarely cheap, but it is the only one-stop path from Phoenix to many of that hub's destinations.

SLC's TSA wait is among the shortest at any major hub; tight connections are usually safe.
