I would *never* call again if that were a viable option, but my experience with chat has always been that for simple fixes it takes much longer than just placing a quick call, and for complex matters I either get told to call reservations, anyway, or they mess up my reservation even worse than a phone agent would. I have somewhat subliminally stopped booking any and all connecting itineraries on Alaska due to the inevitability of schedule changes that will force me to call reservations and roll the dice on having my valid ticket voided by a disgruntled or incompetent agent, which happens approximately once every 4 years to me (only on Alaska, never ever with any other airline).
Of course, 99.9999% of these issues would be completely moot if Alaska could get IT in place with the same basic levels of common sense, do-it-yourself IROPS handling that virtually every other airline has been doing for years, if not decades. Sorry about the rant, but seriously, this is the one issue that negatively impacts the number of Alaska flights I purchase and should have been a priority for them to address long before I even flew my very first Alaska flight circa 2011 or so.
