Cultural Tip
In many Spanish‑speaking countries the informal ‘tu’ is used with friends, family, or when the service staff invites a relaxed tone. In hotels or airlines, staff often switch to the formal ‘su’ to show respect. Also, reservation numbers are usually read digit by digit, not as a whole word, so say ‘X‑I‑Z‑uno‑dos‑tres’ rather than trying to pronounce the whole string as a word.
