So that's about a 15 min difference on a 1000 mile route. A few knots really doesn't make a big difference on time. Some of our customers insist on having the citation X no matter the trip length. It really only makes a difference on long flights. Coast to coast where we r 45 mins faster. I'd take the speed loss and have deice for emergencies any time.
