As a shorthaul pilot at BA, I got a tripline for June, and every month previous to that for the last 4 years, except 1....I think was through choice. Yes BA have tweaked the ruleset somewhat, but only if you bid low on credited hours on a month. I strategically block all my work up at the beginning of the month so as to avoid a forced assigned trip at the end of the month which seem to be few and far between. Certainly not 100% blind lines on shorthaul. Probably 25% blindlines but for someone getting in now, would only be in that territory for a matter of a few months.
