The graphic in #22 and #24 is eye catching but the bird is hard to distinguish when small and people are asking me what it symbolizes. I do not care for the illustration in #21 or #23.
Nice revisions! I like the simplicity of #34 but some others I shows it to said it made them think of American Airlines.
I love the simplicity and symbolism of #35. When I look at it I see a 3-D box, suggesting we are out of the box, and I also see < and > symbols.
#33 caught my eye because it has sharp crisp lines but also feels similar to the lower case letter a. I don't love it enough to rank it high, but there may be something there to build on.
