My and the missus flown from UK to Mexico, Jamacia ,Mauritius ,Maldives which we're all over 9 hour flights , all flight we're when out of cycle as I won't fly when in cycle . I got hit once when we flow to Mexico , my missus is very cautious when we fly and always make sure I travel with triptan injections so when I got hit I injected aborted the attack , I was worried the flight had brought on a cycle but it hadn't we landed and we we're able to enjoy are holiday
