I had a few “jeez we’re using a lot of runway” moments in BOI and BZN in the summer. Or using it on way longer legs than it should have been used, like DAL-SEA or MKE-SEA.The E-jets do both as well (T/O-1 and -2 fixed thrust modes, plus flexible/AT). But I never thought that airplane short on thrust except in Denver on a hot day going farther, etc.
