Given that this is a LONEx, you can save literally hundreds per ticket by flying trans-Atlantic from anywhere other than LHR, and by avoiding flying TATL airlines such as BA that charge outrageously high fuel fines. For example AA flights direct from BRU, CDG, MAD, MXP etc. avoid the UK APD and the absurdly high fuel fines. In economy AA is no worse (but also no better) than the high fuel surcharge airlines, and direct flights from Europe often take little longer than flights from LHR (due to LHR's congestion and related runway delays). In Business class BA offers a superior product that is often worth the premium, but in coach LHR departure avoidance currently results in very meaningful savings.
