I usually fly AA so unsure how AS runs their show.

Flying with my dad who has mobility issues so I booked premium seats close to the front of the plane. (737 Max SEA-HNL) I notice that that bathrooms are all the way at the back and none mid cabin. Are the flight attendants going to cause an issue with sending him through the first class cabin to use the up front ones? I know on AA with normal domestic narrowbody flights they are good with any cabin. (Minus the 32B planes)
