It's annoying to get a notice that you have to call and it ends up being a 1 minute change in an arrival or departure. But this week I got an email from AS for the outbound and inbound for some award travel to Europe in late March/mid April. The changes were 25 mins earlier on the outbound from ANC (well worth knowing about!), 10 mins later departure from SEA, 5 mins earlier departure from LHR a few days later; on the return 5 mins later departure to LHR and no changes to the rest of the inbound. The only one that seems somewhat critical to me is the 25 mins earlier departure from ANC and I wonder if that's why I got the emails. Manage my booking does not require me to call before I can access my itineraries. That's an improvement! Maybe they are changing the system?
