E-Jets are among the better options in the game. The E90 and E95 are better than the E70 and E75, but for fleet commonality and to eliminate a fleet group, they are generally still profitable (more so than the similar sized CR7 and CR9)
Edit: Oatmeal, I operated about 90 various E-Jets in MT4, mostly E95's but had 12 E70's and 10 E75's. All models made money while leased with fuel poking over $1200, and at any fuel price when owned. DO NOT use the e70's and 75's on anything over ~800nm and try to get AT LEAST 3 returns a day for each frame. The 90's and 95's are more forgiving and can make money with 2 daily returns.
