This is not a common issue, but I'll request it nonetheless: when I travel, I use the Google Voice app for making calls (over data). In the airline section, please consider showing the airline phone number in a way that can be copied to the clipboard (so it can be pasted into the GV app dialer), instead of just the button to dial.

Another request is to have more data and less map shown by default. Right now the initial display is about 50/50 of map to data. Consider changing that to maybe 25% top is map, and then 75% is the flight info, with the ability to show more map if desired. The map is pretty, but what I really need to see is flight info.
