Continuity mistake: Jin is handcuffed in season 1, "House of the Rising Sun" and the cuff remains on his left wrist until season 2, "What Kate Did" when Locke removes it. The handcuffs have a distinctive shape - a single strand connected via pivot to a double strand with the lock area. When Jin is initially cuffed to the plane wreckage, the single strand faces out at his wrist, but in following shots, in this and all the subsequent episodes, the handcuff actually switches sides repeatedly, going round his wrist the opposite way.
Continuity mistake: On the airplane, the same passengers are seen in numerous shots with different main characters, and purportedly Kate and Marshal Mars (row 25) are in the same cabin on the opposite side of Jack, Rose and Locke (rows 23 & 24), yet are not seen in shots where they should be seen - though in shots of Jack and Rose, during the turbulance, the same woman and man (behind Locke) fly up as in the Kate and marshal shot. Some examples: When Kate and the marshal are shown during the turbulance, note the red-haired man with the black shirt beside the marshal and other men behind, and in one shot of Kate and the marshal, a woman and man both fly up to the ceiling of the cabin. In some shots of the turbulance, when the red-haired man is seen, the marshal and Kate are gone, replaced by other passengers. Just before the tail section breaks off, men behind the red-haired guy have either changed seats or disappeared, and so forth. Row numbers seen on the luggage compartments overhead are inconsistent with passenger seating. Such as when the tail section breaks off, the man is pulled out from row 26, yet the number above reads 13, or when Claire boards the numbers overhead are 20, 21, 22, yet Jack is in row 23, which is the second row behind the wall. The interiors of the Oceanic airplane also significantly differ in various shots. One example - the seats on the airplane have blue square velcro coverings on the passengers' seat headrests, and long, wide magazine racks on the divider wall behind Locke, but when they carry Locke onto the airplane, they don't exist.
Continuity mistake: In the earlier shows, the positions of the cuts on Kate's and Jack's faces change, as well as their characteristics.
Continuity mistake: The white tape round Charlie's fingers, that first read "fate" and later "late", drastically change their appearance - such as the size and shape of the letters, and the color and condition of the tape, in numerous consecutive shots.
