OK, I have a little more info. NW airline only supplies oxygen on the plane. So we would need our own oxygen at the departure airport (FNT) and arrival (TPA). His doc will sign an order for his in-flight oxygen.
His doctor said he can go commercial jet, so that is my target. NW said that someone on oxygen would usually be assigned a window seat. I thought that since he's not real ambulatory, an aisle seat would be better. And I could sit next to him in window seat and climb over him if necessary. Or if a light load, I could sit in aisle seat across from him.
The plane is a NW DC9-30. I thought first class would be more comfortable for him than coach. But some of the coach seats have the aisle armrest that folds up so it might be easier for him to get into a coach seat than first class. Do they usually put disabled folks in the bulkhead rows? I don't like bulkhead personally, so I never noticed if they have more legroom.
I'll be on the same plane this weekend so I'll investigate & ask F/A.
Any ideas?
