What is the most idiomatic translation of "how often" into Spanish in questions like:
- How often do the buses stop here?
- How often does it rain in November?
- How often do you get headaches?
- How often do flights get cancelled at this airport?
The dictionary translation is con que frecuencia, but is that the only way to translate "how often"? Are questions like this in Spanish usually structured like their English equivalents, or are questions reworded to avoid the sense of "how often"?
