Airlines and tour operators cannot refuse to carry passengers (or take bookings), on the basis of reduced mobility. However this only applies to flights from airports in the EU. Under Regulation (EC) No 1107/2006,
a reservation or boarding can only be refused for justified safety reasons. This also includes if the boarding or transport of a person with a disability or reduced mobility is physically impossible, either due to the size of the aircraft or its doors. If a person is refused a reservation, an acceptable alternative must be offered. If boarding is refused, the person must be offered either a refund or an alternative flight. Airport authorities must provide assistance without extra cost to the person concerned, but it may levy a charge on all passengers.
