This is from Denver International and Houston (Bush).  I didn't have to
tell them at all.  I walked in with my cane, and then at check in, the
ticket girl (and guy) asked if I needed a chair.  I said no at the
desk, but when I got to the security area, the guard asked, and I said
yes.  I hadn't realized how quickly I'd get tired.

They brought the wheelchair and the person to navigate it to me.  On
the flight, I just asked the stewardess (air hostess) and she "called
ahead" and they had a person with the chair waiting for me at
debarkation (if that's even a word).

Depending on how you access the plane, in Houston it was one of those
"jetways" that attaches to the plane, they just wheeled the chair all
the way to the door on the jet.  Was quite nice.  If you aren't fond of
wheelchairs, they also have those electric carts (that hold 4 or 5
people) that run back and forth.  Just ask the hostess (on the plane)
or someone at the ticket counter (in the airport).

Jen just flew Jet Blue from San Jose to Boston and will
fly it back from Kennedy [the bride's maids all went
into the city via bus $11 per person to continue the
partying for Danielle]. She says she will never, ever,
ever fly anything but Jet Blue again. The front of the
plane has a bit less room she says - so if you want
front it will cost you in leg room. She was middle of
the plane and could cross and uncross her legs without
taking out a loan. The seat back in front of everyone
has a built in TV with 40 channels. The flight
attendants bent over backward being sure everyone was
happy and comfortable. She said when the 'peanuts' were
to be passed out, it turned out it was animal crackers,
dorito's, almonds, and about 5 other things to choose
from. If you wanted two, they gave them to you. She was
waiting for the bathroom about half way here and kind
of holding her arms around herself. Steward asked if
she was cold to which she said yes. He wanted to know
if she wanted a blanket and she said she had one and
didn't want to be greedy. To which he said, we want you
to be comfortable. She said when she went into the
bathroom, it was obvious that it had been cleaned
recently which means they had cleaned it during the flight.
I am thinking Jet Blue. :) Does it go to Seattle?  BTW,
she said she had gotten an $89 one way to Boston.
Guessing it was a special but you almost can't not go
for that price.
Duckie who does not own Jet blue but sure is thinking
about maybe looking at the stock price.

Oh - wheelchairs. Book it when you book the flight.
They usually bring one to me at check in even if that
is curb side. Sometimes they tell me to wait inside and
they will call but I don't have to walk too much. They
take you to the right gate and leave you there usually
pointing you out to gate attendants or putting you
close enough that the gate attendant will not miss you.
I tip anywhere from $5 to $20 depending on how much
walking the person has had to do. At Logan, it could
mean miles inside the terminal, down to baggage claim,
get bags and then out to the limo stand which might
mean another mile of walking pushing me and the bag.
{the little weekender I put on the arm of the
wheelchair - a bigger bag they have to pull}.
Once I got in a pickle when they changed gates and
there I was with no way to get the mile beyond. Did
finally find someone to tell so they could get me where
I needed to go but that is rare. There is one idiot
airline where we changed planes that said they didn't
have wheelchairs, all I would have to do was walk two
miles to the carts and they would take me. I said - if
I could walk two miles, I wouldn't NEED a wheelchair.
They didn't get it.  And once in Europe, the language
barrier nearly got me stranded but I finally shoved the
ticket into someone's face and then they panicked for
me. lol
The wheelchair is really the way to go to and fro.
Highly recommend it.

Depending on where you book your ticket, you may be able to tell that party
that you require a wheelchair.  If not that, when you get to the crubside
check in, tell them.  They will get it for you, and they take you wherever
you need to go.  At the gate, I was left in the wheelchair so I could be
rolled to the door of the plane.  I would never make it through an airport
without the wheelchair.  I keep some small bills in my pocket so I can tip
whoever helps me.
