HT, your last post got me thinking about all my flights and I realise that 3 of the 4 times I felt genuinely let down by any aspect of an airline's service happened on US carriers, and 2 of these on the same carrier; however, even those airlines were fine on other flights with them. The other poor service was with an Eastern European airline in the 1980s, but then things over there did need a different level of expectations back then!
