Flyertalk isn't all curmudgeons. It runs the gamut. There are compliments and positive postings, too. I seem to recall the ones who complained about those two routes were regulars and had all sorts of postings. They just said those two stood out as real losers for BA in the service department.
But the 10,000th thread of "why can't i choose my seat when i bought my ticket" does wear me out sometimes. Not to mention the "can i take a baby into the upper deck" to which the regulars will scream in horror and abuse the poor parent to entertain themselves a bit.
But they do not seem in the least concerned over there about the current strike ballot. Most of us didn't experience much disruption during the last strikes. A changed flight time on the same day, maybe, not much more.
Only the newbies to BA will fret this time. Or those taking a complicated trip of a lifetime--it's hardest on them.
