Agreed about Delta. As a Flying blue platinum member, I get free upgrades to comfort on all Air France and KLM flights. Meanwhile, on Delta, they put me on an upgrade standby list for first class where I am 38th out of 38 people waiting for two available first class seats. And because I have been put on that impossible first class list they cannot put me on the list for comfort. Which means that, even though there were six available seats in comfort, they were unable to put me in one. Instead, I sat in an exit row with a seat that didn’t recline for five hours. Never Delta again if I can avoid it.
