I have had the pleasure of flying in standing room twice: once from Cairo to Aswan many years ago as a student - and once fairly recently in Cambodia from Phnom Penh to Battambang. Both were short haul flights of less than an hour in duration.

On the Egyptian flight they had harnesses for children between the windows so you could strap them up against the fuselage.

I think as long as the pilots recognize this and don't do any fancy flying - and as long as the runways are long enough that the angle of climb can be quite flat - well why not?
