Has anyone used this route to fly to Nepal? I am thinking about booking a flight from Chicago to Delhi for my mom and have my brother arrive at New Delhi taking KTM-New Delhi flight to pick her up? My mom doesn't speak any English, so I figured it would be easier this way. Where I am confused is once my brother lands at New Delhi airport from KTM-New Delhi Flight, will he be able to get get hold of my mom who has landed USA-New Delhi flight? I want to make sure he is able to get to the place where my mom gets off the plane and pick her up from there?

Or would wheelchair be a safer option here?

Thanks in advance for your suggestions..
