there are 12 BACF flights in and out of GLA this weekend some of which are Barrhead travel exclusive charters. After the debacle that was the BA Mainline EDI-IBZ failed experiment, if the likes of Barrhead Travel were to take seats on BA as-is you would wonder why a seasonal BACF scheduled flight couldn't be offered, particularly to ie PMI where there are 4 EMB 190 flights alone today along with Milan, Verona, Malaga, Salzburg, Mahon and Ibiza.
Could generate additional income. It's probably the perfect size aircraft (I suspect A319 mainline might just be too big)
