After saving Avios for a long time I am trying to book BA First Class flights to Las Vegas in May 2014. BA do not release the flights until 355 days before and even then they do not show any First Class seats. I phoned the BA Exectutive Club - they were no help as they do not know when any First Class seats will become available or how many.
Are BA Avios a big con unless you are completely flexible on dates and destinations? Or does anyone know how I can book the flights I want?
