Looking at the BA timetable, operations are currently with 9 aircraft - 6 Embraer 170s, and one each of a 190, an RJ85, and an RJ100.
With four more Embraer 190s due this year there is an increase in capability beyond replacing the last two Avros. Which new operations are in prospect ? Which routes are doing well with loads to need their 170 replacing with a 190 ?
