Hello, I chose to upgrade my seat for the lengthy flight home at the last minute while I was on my way to Tokyo for a conference. It's always difficult to know where to go for upgrades in a new place. I was able to locate the appropriate airline office in my area with ease thanks to AirlineCityOffices. The employees were helpful and friendly, and the update process went smoothly. I didn't have to worry about making a ton of calls or looking for the correct information, so I could go home in ease. It was among the simplest travel improvements I've ever encountered.
