Besides what was already posted, there is some information about air travel with a wheelchair/
ECV/disability in the last post on page 1 of the disABILITIES FAQs.
You can find that thread near the top of this board or follow the link in my signature.
The travel thread also has pictures of the aisle chair that Cheshire Figment mentioned.
The first post on page 2 of the disABILITIES FAQs has information about travel on DME buses with a wheelchair or ECV.
Just to clarify - Hoverround makes both
ECVs and power wheelchairs.
ECVs are usually light in weight and could possibly be put in the luggage compartment of the DME bus ( depending on how heavy it is). So, if she has a Hoverround ECV, she would have the choice of using the lift or having the ECV placed under the bus if she is able to climb the steps to get into the bus.
A power wheelchair would need to be loaded into the seating area using the lift because the are generally heavier ( has she thought about getting it to the airport - I know someone who got a power wheelchair and then realized she had no ramp to get into and out of her house (two steps to get into the house) and no way to get it into her vehicle.
Many ECVs can be taken apart into smaller pieces to load into a vehicle.
It sound to me like she may not have gotten it yet since you written she is finally getting one?
If she has not gotten it yet, I have a couple of suggestions:
1) ask the service/delivery person if they have any suggestns for preparing it for air travel. For example, we talked with the wheelchair tech for my DD's power wheelchair about travel and he showed us how to remove the joystick and pack it for travel. It is the most fragile piece, so protecting it is quite important.
2) check if she got the transport option. This is a set of permanently installed heavy metal loops that are meant for attaching the tiedown hooks that attach wheelchairs to the buses. If she does not have that option, check with the delivery person to find good spots to attach the tiedown hooks. My DD's power wheelchair has the transport option - this makes it faster and safer to tie the wheelchair down in the bus. Her manual wheelchair does not have that option, so we marked the safe tiedown spots with flourescent green duct tape.
3) have her practice, practice, practice. It takes a longer time and more practice to learn to drive a power wheelchair than an ECV. Whichever she has, she will wants to get comfortable driving it forward, backing up, turning in both directions and parallel parking it for getting it into place in the bus.
