Continuity mistake: The bearded man sitting next to Jonah, on the flight to New York, is also seen sitting two seats away from Sam when he flies to New York chasing Jonah. The same guy is on two different planes at the same time.
Continuity mistake: When Jonah and Sam are seeing Victoria off at the airport, where does she go? During the scene other people are moving towards and around the door that Victoria seems pointed towards; however, in the shot that immediately follows her departure the doors are opened by the flight crew and passengers (including Annie) disembark.

Continuity mistake: Annie is discussing her trip to Seattle with Becky at her house. She pulls out the tape of "An Affair to Remember", walks into her kitchen, and Becky puts Annie's things on the table, handbag on the left and the purse to the right. They go back to the living room, then return to the kitchen a couple of minutes later. In the shot when Annie puts her mug down, the purse is now on the left and the handbag is on the right.
