Fits under-seat on which airlines?

Manufacturer dimensions compared with the cabin carrier limit on each of our airline pages. Length and width may be swapped (the carrier can be turned); height may not. Soft carriers may squash a little, but we only compare published numbers. The gate agent has the final say.
