If you've had a long day, your OH's daughter must have had an even longer one! Direct flights from Canada (Toronto) to Stansted don't start until the end of the month. When they do, they'll take 8½ hours, so she must have had an even longer journey involving connecting flights (possibly changing planes in the USA?). Then she'd still got a long drive ahead of her.
Get her to ask us about the best route in future (because Stansted isn't that close to Torquay!). Doing the first sector from Canada into Amsterdam, Dublin, Paris CDG, Edinburgh or Manchester, followed by a short hop into Exeter, would make far more sense!
At least she got into Stansted at a sensible hour though. Whenever my friends ask me to pick them up from there it's usually around midnight (or even later after flight delays).
