"So you're saying bmi are using a BIGGER aircraft on an OFF-peak flight????? And a SMALLER aircraft on PEAK flights??? "
On closer inspection it appears that the based 319 will in fact be a 320 this summer, the only 319 flights being BD418 and 419 in the afternoon. Saturday is all 145's as is Sunday except for BD419 and 420 when the 320 reappears.
