How to interpret “what terminal?”

If someone just asks “what terminal?” , it’s usually about travel:

  • At an airport : They’re asking “Which terminal does the flight leave from or arrive at?”
  • At a bus/train station : “Which terminal or station building should I go to?”

In a programming or tech forum, the same phrase might mean:

  • “Which terminal app are you using?” (e.g., macOS Terminal, Windows Terminal, iTerm2, etc.)

If you tell me the sentence you saw “what terminal” in (e.g., an airport text, a code tutorial, a meme), I can pinpoint the exact meaning for that situation.
