Airport submission pages have a comment functionality. If you leave a comment on your phone, the submit button (“SEND COMMENT”) is directly underneath the text box for the comment:
It would be very, very easy for a finger that’s trying to place the cursor somewhere on the bottom row of the box to accidentally press the button.
I think it would be an improvement if the button were one row of text lower, giving some space between the text area and the button.
Note: This feedback applies to any future comment boxes, as well. For example, if there ends up being a comments feature in the Wanted Airports tab, having the submit button one row of text away would be helpful, as well.
