In a review in the Entertainment Weekly magazine, the song received a "B+" rating. The review commented that the song is a "surprisingly lovely pop-punk pounder about intercontinental relationships." Joe DeAndrea from Absolute Punk said that "Jet Lag is Simple Plan's first big single in a long time, almost in vein of No Pads' "I'd Do Anything." Not as rocking, but packs the same similar punch." Davey Boy from Sputnikmusic was also positive, saying that "English pop songstress Natasha Bedingfield fares best with the call and response vocals of 'Jet Lag' making for an effective radio pop-rocker that plies the oft-used theme of long-distance relationships."
The music video for "Jet Lag" was released on May 4, 2011 which features Natasha Bedingfield in a hotel room, and the band at Toronto Pearson International Airport. The band performs within the airport while Pierre Bouvier gets ready for boarding the flight to his girlfriend, who is played by Natasha Bedingfield.
