Passengers hoped the flight would allow them to “time travel” and ring in the New Year twice… but they arrived in the wrong year.

(CNN) — Passengers on a United Airlines flight hoping to “travel back in time” to celebrate the New Year are off to a bad start to 2024.

Flight UA200 was originally scheduled to depart Guam at 7:35 a.m. on Jan. 1, 2024, and land in Honolulu, Hawaii at 6:50 p.m. on Dec. 31, 2023, crossing time zones to pick up passengers a year ago.

“You only live once, but you can celebrate the New Year twice!” United Airlines tweeted earlier this week. In another Instagram post about flight UA200, he wrote: “Time travel is real.”

Each year, several flights offer passengers the opportunity to repeat New Year’s celebrations, and airline crews sometimes celebrate the occasion multiple times on the same route.

But UA200 passengers were disappointed. The flight was delayed, departing Guam at 1:49 p.m. on Jan. 1 and arriving in Honolulu at 12:34 p.m. on Jan. 1, missing the countdown.

Several passengers later expressed their complaints on X, formerly Twitter.

“Great idea, too bad it got delayed! I had to take this flight. Double New Year’s is no longer possible,” one person wrote under the original United Airlines tweet.

“I booked this flight specifically so I could do this,” another comment read. “I have received notice of a delay and we are not scheduled to arrive until January 1st.”

The airline responded to X by offering passengers rebooking assistance.

Passengers on other one-off flights had better luck, such as Cathay Pacific flight CX872, which departed Hong Kong shortly after 1 a.m. on Jan. 1 and arrived in San Francisco at 8:22 p.m. on Dec. 31; and All Nippon Airways flight NH106, which departed Tokyo at 00:48 on January 1 and landed in Los Angeles at 17:12 on December 31.
