The cost for a pre-assigned seat on a trans-atlantic flight in coach or premium economy class is $30 USD per flight! Passengers traveling on a discounted business class must pay $90 per flight! For exit row seats the fee is $75 each way! These fees are non-refundable.
No U.S. Airlines have started charing for seat assignments yet, but they most likely will start soon.
This is a perfect example why to use a Travel Agent for international travel. Most Travel Agencies can still book British flights without charging for seat assignments.
