what u think, can an illiterate senior citizen 60+ travel usa n get back nepal on his own ?? i heard there is wheelchair service for senior citizen but haven't have much idea about it...expertise/experienced ideas highly appreciated

tks

Try China Southern Airline
Book cheap ticket.
email them with passport copy your contact detail and ticket at flychinasouthern@csair.com
They will setup everything perfect, ask your parents to keep some $5/10 bills , they expect tips ..
I did for my parents never disappointed.

thk gaulejetho information was helpful..any idea if they help in transit like changing the plane n other thing ..also what about immigration..like for us we have to wait long queue n answer multiple question ...how these citizen clear immigration especially when u cant speak english ?

changing the plane n other things: they will take care just ask her/him to stay calm
immigration: Ask them to stay quite, broken English might not be good, they will figured it out, they have separate systems no long line.
Officer usually does not create trouble, in my case officer did not ask anything my grand mom was around 78 during visit so no worry at all.
Good luck and best wish...

I did wheelchair for my mom few years ago, flying through Korea. She got received from the flight from KTM. Nobody showed up to pick her up from the rest area to take her to her flight to US. Luckily she met some good Nepali folks travelling together, so wasn't big issue. Even here in US, I have to do wheelchair for my mom every time she flies by herself domestic. There have been couple of incidents where nobody showed up to pick her up. So, I wouldn't rely on wheelchair completely, well if I had option..
