The flip side is SEA-EAT, SEA-BLI, and SEA-YYJ, all under 100 miles (but very nice to do as flights because mountains, driving the length of the Seattle metro area, and water respectively make the drive non-trivial), flights for which the E175 is overkill and which have been dramatically reduced with the disappearance of the Q400. The E175 is a great plane for the 1500 mile missions (I'll take it over a 6-abreast mainline flight any day of the week), but the Q400 is brilliant for the 95 mile ones.
