Alias's allusions to Lost
- Alias season 4 episode "A Clean Conscience" features a scene set in LAX. A boarding announcement for "Oceanic Airlines to Sydney" can be heard over the loudspeaker.
- Nikki's show Expose bears several resemblances to Alias. Both have one word titles with 3 syllables. Nikki is posing as an undercover stripper and ultimately learns that the person she is working for is the villain she has been trying to uncover. Sydney frequently went undercover in a wide range of disguises, many of them sexy, and likewise learned that her boss Arvin Sloane was evil.
- A recurring theme in Alias is the number 47, much like the Numbers in Lost.
- In the last season of Alias, a pregnant Sydney is kidnapped and finds herself in an operating room. In Lost, Claire has had an almost identical experience.
- Sydney has issues with both of her parents, much like all main Lost characters, who have major parental problems as well.
- Locke's closing remarks in "The Man from Tallahassee", "Dad?", mimics the line of dialogue given by Sydney Bristow in an early episode ("Dad?"). Both lines were delivered at the end of an episode when the character sees their father in an unexpected situation. This is also similar to Jack saying "Dad?" in "White Rabbit", the Swan computer reading "Dad?" in "What Kate Did", and Claire saying "Dad?" in "Something Nice Back Home".
- The Season 1 finale of Alias and the Season 3 finale of Lost featured similar situations. In both instances, a leading man (Charlie in Lost and Vaughn in Alias) is confined to an area that is flooding. Both men look through a glass window to a person who is watching from the other side who is in considerably less danger (Sydney in Alias and Desmond in Lost). In both cases, the onlookers try to smash the glass window with a nearby fire extinguisher and fail to do so.
- In the Season 5 finale of Alias Tom Grace uses a cylinder of liquid nitrogen to delay the explosion of a big pile of C4 in exactly the same way that Michael does in the Season 4 finale of Lost.
