After the plane lands it can clearly be seen as branded "Las Vegas Air" but when plane has been released near end of episode it is branded as "Trade World".
The deceased, Tony Candlewell's, age is given as 30. One shot shows a close up of his drivers license which shows his date of birth as 06-18-75. This episode was from 2000 meaning he was only 25!
While discussing the Mile High Club aboard the aircraft, Sara Sidle tells Gil Grissom she joined the club aboard Delta Airlines flight 1109, Boston to Miami. Delta Airlines flight 1109 actually services Salt Lake City to Las Vegas.
On approach, the airplane asks for a runway. The control tower states runway 15. However, there is no runway 15 at any airport in Las Vegas that a commercial plane could land at.
