if it is in regards to completing airport formality just book her a wheel chair with the airline she is going to travel. they will take care of everything from point A to B.
If she is not actually disabled they may not take her. There are limited resources and wheelchairs and actual sick and disabled people who need the wheelchair. You can give her a note with her information and questions in English and Punjabi and she can approach an airport employee. I need to make my connection to city X in Canada departing at Y time.
You have the wrong information it is not like that . There is no limitation to wheelchairs . One should just book it along with travel ticket as simple as that.
