The Ritchey's are no doubt great bikes but:
The Ritchey bag appears to be 26" x 29" x 9" so the sum of dimensions is 64" which is I believe above the airline legal size and according to the OP, "My main concern is I want to be able to fit it in one suitcase that is airline legal, for weight and size."
Also, I'm not not convinced that they would be more comfortable than a Birdy if the road is a bit rough. This may or may not be important depending upon the individual.
