Cultural Tip
In many Spanish‑speaking countries reservation numbers are often alphanumeric (e.g., 4521‑AB). When speaking to strangers or in formal settings, use the formal possessive 'su' instead of 'tu' and add 'por favor' to keep the tone courteous. Also, remember that the accent on '¿Cuál?' distinguishes it from the non‑question word 'cual' (which is rarely used).
