Next month will fly LHR > ATL & return, a trip I make 3 - 4 times pa. I fly economy, always Delta, and have a silver card, which has a benefit valuable to me - no stated limit on your checked bag weight - I am usually 2 or so kilos over. For first time ever Delta.com booking has put me on Virgin Atlantic, who, I am told, gives no benefits to Delta silver card holders. So I lose that excess weight concession. Comments?:
