During the establishing shot at San Francisco Airport, we see a United Airlines jet crossing the screen. The first mistake is the artwork on the plane. It's painted in the color scheme after the merger with Continental in 2012. Not either of the color schemes in the fleet in the mid 90's.
Second, is the plane appears to be an Airbus A319 or A320 which did not enter United's fleet until after 1995.

All of the scenes showing a typewriter used up close it is a manual typewriter. The sound effect is from an IBM selectric typewriter which uses a totally different mechanism than a manual typewriter.
(At around 16 min) The scene shows a United jetliner at the San Francisco, CA airport of 1995. The United aircraft logo includes the Continental globe, which was adopted after the United and Continental merger in 2010. A United aircraft in 1995 would have used the Tulip, the pre-merger logo used by United.
One of the scenes is preceded by a shot of SFO airport, with the lettering "1995 - San Francisco, CA". A United Airlines plane on the tarmac is painted with a livery that was only introduced in 2010 (after the merger with Continental).
