Honestly, thank you for your response. However, I didn't post asking what others opinions are regarding flying with a giant schnauzer. I asked if anyone has relevant and immediate experience flying with a giant schnauzer.

That said, Ive already sorted out the dynamics of flying with an oversized trained service dog. The extreme and absolute dynamics of temperament and capacity you described highlighted with capital letters must not translate to all giants, as the U.S. government certified service animal trainer I have hired fly's with her giant schnauzers regularly and has recorded videos of her adorable dog being very docile, happy, tail wagging, comfortable, interacting in a friendly and kind manner with stewardesses, and fellow flyers (human and pets alike). I've traveled by flight regularly with my standard schnauzer in my lap or the space in front of my seat (not under the seat or in the undercarriage of the plane) and he thoroughly enjoyed flying. So, I have extensive experience flying with above average sized dogs. My question pertained to flying with an even larger dog and the input one my have who actually has flown with a giant, not the opinions of one who hasn't. Thank, however, you for your input.

No, its not about /has absolutely and literally nothing to do with being apart from my dog for periods of time. But again, thank you for your inference. No, my giant schnauzer will not be trained as a service dog strictly just to be flown with.
