“no one says I got a letter via the Royal Mail.”
Except the website royalmail.com which says that you can send letters or postcards of up to 2kg “via air mail”.
Ah, but “via air mail” is a phrase denoting a specific separate service from the “ordinary” post, and in any case I think colloqually Britons would say “I sent it air mail” or “I sent it by air mail” rather than “I sent it via air mail”. Indeed, our airmail envelopes always said “By air mail” rather than “via”. (They also said “Par avion, too …)
