After the fight scene in the airplane bathroom the knife next to the sink disappears. When Eliot and Nathan go back to try and wake Erlick up the knife has returned.
The team is clearly breaking into GenoGrow at night, and the flight they are to catch leaves "in an hour" - yet it is clearly daytime when they arrive at the airport. An hour is not enough time to go from full night to full day.
However, the time stamp when they begun the break in says "4:10am" (just prior to Sophie asking the guards whether the rave is there) and the exterior shot of the city appears as though daylight is just starting to light the horizon. Depending on how long it took them to acquire the information (and they had to walk up to the 30th floor from the ground level, evidenced by the "G" on the elevator) it is not unlikely that an hour from when they left the building to arriving at the airport is ample time for day to break.

Watch the knife. When Eliot leaves the restroom the first time the knife is not there. When he and Nate return the knife is there and Eliot takes it when they leave.
Eliot pretends to be a Federal Air Marshal, but is sitting in Coach. FAMs always sit in First Class. Their mission is to prevent any threats to the cockpit, which can only effectively be accomplished from First Class. Other LEOs permitted to fly armed will sit anywhere on the place except for those with a detainee. LEOs on escort duty of a detainee always sit in the very rear of the plane, again to keep any potential threats away from the cockpit and because they sometimes will load from the tarmac.
Parker goes into the plane's hold to look through the checked baggage; but checked baggage is put in unpressurized cargo holds. She wouldn't be able to survive, much less breathe normally and move around.
After the plane lands on the bridge, a long shot shows the plane and the passengers walking away from it. How did they get off? There is no sign of the emergency exit slide, and jets don't have a set of stairs.
As the team rushes out of GenGrow toward the airport, several B-roll stock shots are used; first, a generic aerial helicopter shot flying over LA, then a medium distance view of an airport showing planes taxiing and lifting off- including a red and white TWA jet. TWA ceased to exist in 2001.
