Quoting the blog author:
Some two years back passengers complained that PIA were charging extra (Rs. 4.5k about $8) for people who requested a wheelchair. It was a big deal because it affects disabled and senior citizens who go on pilgrimages to Mecca. One even saw a passenger wheeling an old lady on a baggage trolley from the PIA check-in to departure area in Jeddah, the “gateway to Makkah and Madinah.” I can only assume that this is no longer true — who would pay that much for this wheelchair? PIA must have come up with this practical solution to buying more costly wheelchairs.
What is interesting is that the European budget airline Ryanair has been reported to charge a “universal wheelchair levy” for the cost of transporting disabled passengers. This came after the airline was sued by a passenger who was charged £18.
Now who can beat the highly innovative minds of Pakistanis?? =)
