This will be provocative: 14 CFR § 382.5. DOT has openly recognized allergies to be a disability covered by the ACAA. This means that airlines must make accommodations for passengers with allergies so that they can fly as safely on planes as any other passenger. Airlines cannot, however, guarantee ...
Jump to postAs far as I understand, issue is with people being a bit paranoic - which I can understand given possible consequences. But there is limited actual danger for remote exposure. Someone in a seat next to allergic person is legitimate, even if borderline only. Few rows away shouldn't be an issue https:...

I have to wonder why large avionics bays haven't gone by the wayside on newer A/C's. No doubt a modern smart phone has more than enough compute power for every system on the aircraft.

Jump to postThe E175 and CR9 are too big for the US market in my opinion, ideally I feel like a jet that fits 6F 70Y would be perfect.
