Charlie Day's Always Sunny stretches into a record 18th season
It's Always Sunny in Philadelphia is back for a record-extending 18th season, with Charlie Day still at the center of the longest-running live-action sitcom. Season 15 broke that record; the 10-episode Season 18 premiered Aug. 17, 2026, at 9 p.m. ET on FX and FXX.
That staying power is the news. The FX comedy about friends who co-own Paddy's Pub, a flagging Irish bar in Philadelphia, is still on the air—and still warning off anyone easily offended. In a mid-2000s on-camera interview quoted by The New Yorker, Rob McElhenney said the series had “no real situation,” only a new mess each week.
They didn't stay away. Season 18 is now a longevity story in the least wellness-coded sense: a sitcom that aged in public without growing up.
Key Takeaways
- The Hollywood Reporter says season 18 is a record-extending 10-episode order after season 15 became the longest-running live-action sitcom.
- Charlie Day remains in the Gang with Glenn Howerton, Rob Mac, Kaitlin Olson, and Danny DeVito.
- IndieWire argues most of season 18 is engineered for maximum disgust, with “Mac and Dennis Tear Their ACLs” as the main exception.
- The two-episode premiere aired Aug. 17 at 9 p.m. ET; remaining episodes continue weekly on Mondays on FXX, with next-day drops on Hulu/Disney+ per THR.
Why is Charlie Day's sitcom still running after 18 seasons?
The Hollywood Reporter frames season 18 as a “record-extending” 18th go-around. Season 15, it notes, broke the record for longest-running live-action sitcom. IndieWire critic Ben Travers puts the series at nearly 200 episodes and still capable of “fresh, new abominations.”
McElhenney's early pitch still describes the engine. Travers credits Howerton, Mac, and Day with distinguishing themselves after all that time. Day plays Charlie; Howerton plays Dennis; Mac (McElhenney in The New Yorker's origin account) plays Mac; Kaitlin Olson plays Dee; Danny DeVito plays Frank.
What does Season 18 look like for the sickos?
Travers grades the season a B and says it is “for the sickos.” The premiere, “Frank Marries a Corpse,” “lives up to the nauseating promise of its title,” he writes, before a follow-up surpasses it. A road-trip episode fails to leave Philadelphia city limits. A Ren Faire episode includes a McPoyle brothers cameo and a closing joke Travers calls distressing.
Two otherwise unrelated episodes pay homage to generations-old I.P. while still out-maiming their inspirations, he writes. The episode that stands apart is “Mac and Dennis Tear Their ACLs.” Dennis and Mac are laid up; only Charlie can help, while Frank and Dee try to reconstruct a plot that involves a Christmas-card competition. Travers says it has a bottle-episode vibe and a guest turn from writer David Hornsby (Cricket).
He argues it is the only season 18 episode not designed to elicit maximum disgust. For viewers who like the show's darkest corners, that hour is the exception in a stand-out run of filth.
Where can you watch Season 18 this week?
IndieWire says the two-episode premiere landed Monday, Aug. 17, at 9 p.m. ET on FX, FXX, and Hulu, with new episodes weekly. The Hollywood Reporter lists the same clock time on FXX (6 p.m. PT / 9 p.m. ET) and a 10-episode Monday schedule of 30-minute installments.
THR says you can livestream FXX on DirecTV, Fubo, and Hulu + Live TV. It also says new episodes drop on a one-day delay on Hulu/Disney+. Prior seasons, 1 through 17, are on Hulu/Disney+ on demand.
Two decades after McElhenney told easily offended viewers they might want to skip it, Charlie Day and the rest of the Gang are still inside Paddy's Pub. The longevity still looks improbable.
