The preposition should be ‘de’, not ‘du’, because it links directly to the noun ‘vol’.

Cultural Tip
In French, the level of formality matters. With strangers, airline staff, or older people, use the polite ‘votre’ instead of ‘ton’. Also, French speakers often add the airline code (e.g., AF for Air France) before the numeric part, so you might hear ‘AF123’ rather than just ‘123’.
