Many times I have paid more for UA as I enjoy their channel 9. On our last trip on UA, from TPA through IAH to SNA we were on a 737 and then a 757, as I recall. I had the earphones, saved from the first flight to IAH but was told I'd have to pay for any audio [on each flight?!-all short hops]. I was very disappointed to be on UA unable to hear channel 9 but since we paid a high fare and had to check in our bags for $25 each to boot [you board only to discover there's no room in the bin for your bag] I was not in the mood to buy audio or food on board. But I shall well remember this when choosing our next flight. This is very bad PR that all the media ads can not counteract.
