I just took a leaf on back to back 250 miles drives from Monterey to Lake Tahoe and back with successive QCs, and experienced none of the charging issues that others are complaining about. Going up to Tahoe, I QC'd 3 times and going home QC's twice. The 2018 LEAF that I drove performed its QCs exactly like my 2014 does.
All QC sessions on ALL BEVs taper their charge rate over the time of the charge. Some do it more aggressively like the Chevy Bolt, and the LEAF tapers it charge rate too, but not unlike earlier versions have always done. Those that are critical of the charge time for the new LEAF are just regurgitating what they have read on the web. I can confirm, that those accusations of slow QC times are inaccurate, misunderstood, or just FUD.
If your commute is 100 miles RT, and you would leave your car at the airport and not charge it there, as long as you left with a full charge you won't have any problem.
The LEAF is a fine car, and the 18 with it's ProPilot features is outstanding. It has the best adaptive cruse control of any car I have driven, and the overall quality of the build is superior to any other BEV with possibly the exception of the e-Golf. I have enough confidence in the 2018 LEAF that I took delivery of a 2018 SL yesterday.
