I wonder if others have seen this. When entering airport codes into the search fields, if I use auto complete feature on my Android keyboard (e.g. I've entered this code before and rather than type it out I tap on the suggested value) then Android appends a trailing space to the code (probably helpfully thinking I am going to keep typing another word). The trailing space stays in the field when I tap into another field. Then when I submit the form, EF tells me it can't find the airport code and I have to go into the field to delete the trailing space.

EF Voice, a simple fix would be to always trim any spaces from this field before executing the search.
