They can bring vaporub and put it under their nose to avoid unwanted smells. I live in a city and do this all the time. You can buy a small tin or stick. Alternatively if they don't like the texture of that I've also used a "Migraine Stick" roll on oil instead of meltable goo.

Fellow migraine sufferer. I have found that magnesium glycinate (500 mg) and this migraine stick also help. Obviously, not going to be as good as prescription drugs, but every tool helps. I have also heard good things about caps that you can freeze and then wear on your head when you have a migraine. The cold causes vasoconstriction and can help as well, but I haven't personally tried it.
