Wheelchair levy makes an enormous profit. Here's the maths:
189 pax paying, I think, 50p. = 94.50GBP: on EVERY flight!!
Airport Cost of wheelchair (shared with airport) = +/- 15GBP for each party.
Max number of wheelchairs per flight = 4.
Most pax who use a wheel chair regularly bring there own, therefore no airport charge.
RYR have 120a/c flying 8 sectors per day. In August they claimed to have flown 4.0m pax each paying 50p, for nothing.
You do the calculation!!!
Add to that the compulsory insurance levy. Wow. If any of this is stopped the profits would take a big hit. Stealth taxes that Gordon would be proud of.
