First delivery is scheduled for July last I read. Give the relatively large E175 schedule they are implementing Aug 1st, they will probably have 4 on force by Aug 1st with some route proving completed in July.
Other initial E175 routes beside YUL
on off-peak and weekend times. The primary route in Aug will be YUL
will 5 dailies.
I dumped at the gybe mark in strong winds when I looked up at a Porter Q400 on finals. Can't stop spotting.
