Many airlines have historically used ISO numerical standard for day-of-week notation in their timetables, which has Monday as day 1 through Sunday as day 7. So a service that operates 2457 is a service that operates Tuesday, Thursday, Friday, and Sunday.

OP posted on Monday, meaning OP was referring to BA274 on Sunday being canceled (quick check of any of the usual flight-tracking sites verifies this) and being rebooked on BA274 on Monday, which is not a day on which BA270 operates. Regardless, OP did not post until 4:45pm local, at which time the LAS check-in counters were presumably already open (not to mention that my reply some 3 hours later was probably not helpful).
