Before departure: doors, slides and cross-checks
"Cabin crew, doors to automatic" — or "arm your doors" — instructs crew to arm the escape slides. With doors armed, opening one inflates the slide automatically for an evacuation; with doors disarmed ("doors to manual") it opens normally at the gate. The dreaded accidental slide deployment you read about happens when someone opens an armed door on the ground.

"Cross-check" — as in "doors to automatic and cross-check" — means each crew member verifies the door opposite or nearest a colleague's station, and the colleague confirms it. It's the crew resource management habit of independent double-checking applied to the most safety-critical pre-departure task.
"Flight time today is six hours and forty minutes" deserves a footnote: crews usually quote airborne time, which excludes taxi. Heathrow to JFK might be quoted at 6:40 with a scheduled block time of 7:55 — the difference is the queue to get off the ground.
In the climb and cruise
"We've reached our cruising level of flight level three-five-zero" — flight levels are altitudes in hundreds of feet above a standard pressure setting, so FL350 is roughly 35,000 feet. Crews use flight levels rather than local-pressure altitudes because at high altitude everyone must share the same pressure reference to keep vertical separation exact.

"We may experience some turbulence ahead; please keep your seatbelts fastened" is usually triggered by a ride report from an aircraft ahead or a forecast area — the crew is acting on information you can't see, which is why the belt advice applies even in smooth air.
"We'll be starting our descent shortly" typically comes around 30–40 minutes before landing, and the initial descent is subtle — a nose-down change in engine note rather than anything dramatic.
Arrival: holds, vectors and finals
"We've been asked to hold for a little while" means the arrival airport can't take you yet — congestion, weather, or a runway change — and the aircraft will fly a racetrack holding pattern until approach control releases it. Each loop takes a few minutes; it's queueing, not malfunctioning.

"We're now on final approach" (or "established on finals") means the aircraft is aligned with the runway, gear and flaps set, descending the last few miles. Landing is minutes away — this is the announcement that sends cabin crew to their jump seats.
Occasionally you'll hear "we're going around": the approach didn't meet stable criteria or the runway wasn't clear, so the crew climbs away to rejoin the queue. A go-around is the system working correctly — the safe, trained option chosen over a rushed landing.
The phrases you'll (almost) never hear
Crews are trained to communicate calmly and precisely under stress, which is why genuine emergencies often sound eerily routine. What you won't hear from the flight deck is anything ambiguous in a real crisis: if there's an evacuation, the commands will be unmistakable and repeated.

Worth knowing: "pan-pan" (urgency) and "mayday" (distress) are radio calls to air traffic control, not passenger announcements. And if the captain ever says "this is the captain speaking, evacuate" — everything up to that point was preamble.
