French Phrase
C'est quoi mon numéro de vol ?
Meaning
You are asking someone (usually airline staff or a travel agent) to tell you the number assigned to your flight. The phrase is useful when you have a ticket or reservation but cannot locate the flight number on the document.
When to use
Use this sentence at the check‑in desk, at the airline’s customer service counter, or when speaking with a fellow traveler if you need to confirm which flight you are on. It works best in informal or semi‑formal settings; in very formal contexts you might choose a more polite formulation.

✕Common Mistakes
C'est quel mon numéro de vol ?
The interrogative "quel" must precede the noun, not follow "c'est". Use "Quel est mon numéro de vol ?" instead.
C'est quoi mon numéro du vol ?
The preposition "de" already links the nouns; adding "du" (de le) is redundant.

Cultural Tip
While "C'est quoi..." is perfectly understandable, native French speakers consider it casual. In airports, especially when speaking to airline staff, opting for "Quel est mon numéro de vol ?" or a polite request with "s’il vous plaît" shows respect and often yields a quicker response. Remember that flight numbers in France usually start with the airline’s two‑letter IATA code (e.g., AF for Air France).
