As of this past Sunday, United is waiving paper ticket fees, Australian Electronic Travel Authority Fees (which up until recently were free), and the $25 same-day confirmed change fees for 1K, Global Services, and passengers flying on paid premium class ickets.
I still miss the days when same-day confirmed changes (not on the day of departure, but well in advance) were no cost to Premier Executive and 1K members. I could book an 8am flight and call up a week later, still long in advance of travel, and change it to a 2pm as long as the same fare class I had ticketed was available on the 2pm (and technically as long as the fare I had purchased wasn’t time or flight specific, but those rules were often ignored).
Still, fee waivers are good, and certainly appropriate for top tier elites.
