He says, “Ladies and gentlemen, we have reached our cruising altitude of 33 thousand feet...” followed by the joke, “33 THOUSAND FEET? Oh shit, man! We fuckin’ higher than Redman at the Source Awards!”

Quick Scoop

In the scene people usually mean, Snoop Dogg’s character Captain Mack keeps it playful and over-the-top while announcing the flight. The quote above is the clearest “before landing” line surfaced in the available results, and it comes from a transcript-style source plus an IMDb character page.

Extra Context

The character also has a few other memorable lines in the film, but they vary by scene rather than landing specifically. One transcript source lists several of his more quoted bits, showing the movie’s intentionally outrageous tone.

TL;DR

The line most people are asking about is: “Ladies and gentlemen, we have reached our cruising altitude of 33 thousand feet...” followed by the “higher than Redman at the Source Awards” punchline.
