As you may or may not be aware, status of 'domiciled' has become more complicated recently. There are various criteria you need to comply with in order to avoid UK income tax and having property empty, schooling, wife living there, length of contract, other family members etc all can conspire to effect your liabilities.
My best advice is to do a few searches and see if there's a common theme and, most importantly, seek professional advice. The Fry Group are used by quite a few pilots, EK, BA & CP and would be a good start. They are probably due a visit next month or so. I'd also then get secondary professional advice just to make sure they're the same and always in writing. I'm sure other posters could recommend someone they use.
Making a rash decision now could have massive implications on your earning potential and personal future wealth. Good luck.
