It really is no big deal. The aircraft does not know where you have been or where you are going. The further from UK the flying gets easier and the ground and planning problems get worse. Stay safe and easy in Europe or more fun to go adventuring intercontinental.
Speaking as one who has done UK to Alaska and Joburg to UK.
Next trip is round the world in July. Life is for living and expanding horizons.
See that Henshaw's record to Capetown and back has been broken after 70 years. Brilliant effort.
