If Charleston has been on your someday-list — or you’re a Lowcountry family eyeing a Southwest getaway — United just made the decision easier. The airline is offering roundtrip flights between Phoenix (PHX) and Charleston, South Carolina (CHS), and vice versa, starting at $254 in Basic Economy or $354 in regular Economy, with all taxes already baked into the price. The deal was flagged by The Flight Deal on July 7, 2026.
Why This Fare Stands Out
A $254 all-in roundtrip on a legacy carrier like United, on a coast-to-coast-ish route like Phoenix–Charleston, is a genuinely good number. The $354 regular Economy fare is worth a look too if you’d rather have standard seat selection and a bit more flexibility than Basic Economy allows.
And because this fare works in both directions, it’s really two deals in one: Phoenix-area travelers get an easy shot at a historic Southern city, while Charleston-area families get a cheap way out to the desert Southwest.
Who This Is Best For
- Phoenix families planning a summer trip who want a coastal, walkable city without the flight costs eating the budget
- Charleston-based travelers looking for an affordable jumping-off point to the Southwest — Phoenix puts you within striking distance of the rest of Arizona
- Budget-minded couples or solo travelers who pack light and don’t mind Basic Economy’s restrictions in exchange for the lower fare
- Anyone with family split between the Carolinas and the Southwest who’s been waiting for airfare to dip before booking a visit
Basic Economy vs. Regular Economy
At $254, Basic Economy will typically mean no advance seat selection and a more restrictive carry-on/change policy — standard for the fare class. If you’re traveling with kids, checking bags, or want the ability to change your trip, the extra $100 for regular Economy at $354 may be the smarter buy. Either way, both fares include all taxes, so the price you see is the price you pay before baggage fees.
A Few Things to Keep in Mind
Flight deals like this one tend to have limited seat inventory and can disappear or reprice within days, so if your travel dates are flexible, it’s worth checking availability soon rather than waiting. As always with Basic Economy, read the fare rules before you book so there are no surprises about carry-ons or changes.
Bottom Line
$254 roundtrip, all taxes included, on a route that normally isn’t cheap — this is worth a look whether you’re flying out of Phoenix or Charleston. Head to United’s site to check specific dates and lock in the fare while it’s live.
