I do not know how BA have the cheek to have this advert on UK tv because if you live outside of London and have to use a shuttle to catch your onward connection then the bag issue in my humble opinion is not so good. I speak from experiance and have given up on BA. However one of my co workers continues with our national flag carrier and still has issues with missed bags and cancelled shuttles and this is all post T5 (Jan 2012 last time he hit problems).
