I have to agree with you Falcon. I have had two experiences with A/V failure on long flights. Both on Delta. I love my children but trying to entertain them for a 9 hour flight is tough. Might be easy for Flyingmom but not me.
I think they should give you something. They won't, but I feel like they should. When Delta told me "tough luck", I took my $50K+/year business to British Airways. It was the best thing because I had no idea how much better BA was than Delta. I am now a loyal BA customer (Gold in 2005!) and I will continue to be until they create misery.
