[UPDATE] My brother [29M] wants me [20F] to pick him up from an airport 5 hours away. I don’t want to. Am I being unreasonable?

Really wanted to let those of you who replied to my first post what happened because you were all very helpful!
I made the original post a few days ago but I didn’t think it’d blow up like it did. I’ll admit, for the sake of anonymity I left out some important details. Not only is my brother not from our town, he is from a different country. It is a bordering country. This is important because he lives in LA and our town is just south of Montreal, Canada. Basically he can save money on his flight by flying domestic. You can probably see where this is going... he wants me to not only pick him up and drop him off, driving 5 hours each way, each time, but wait in line to cross the border, not once, not twice, but four times so he can fly from LA to NYC (~$350) rather than from LA to Montreal (~$600). I would then have to drive from Montreal to NYC, pick him up, and drive him back. Rinse and repeat after the reunion. So yes, everyone was right, he was being a jerk in even asking.
I don’t want to be a doormat but I also wanted to avoid saying outright that he was being unreasonable and I didn’t want to do it. Half because I didn’t want to cause any drama before the reunion and half because I wanted to avoid him telling my relatives I didn’t do it because I was being a terrible sister (not that they’d side with him).
Irrelevant but my mom’s been working pretty hard lately. So... I booked a full day at the spa and hair salon for my mom and I, paid in full, and to my brother I said — “sorry, but I already have plans for that day. Mom and I are going to the spa and hair salon. It’s a surprise for her since she’s been working so hard lately and if we cancelled, our cancellation fee would be almost as much as the $200 you’re saving. Could you catch a Greyhound? If not you’ll have to ask someone else to drive you.†I knew he’d go to my mom next if I said no to driving him so I thought this would knock out putting pressure on her if he did.
He whined and nagged and eventually just asked me if I could drop him off after the reunion. Though this was a slightly more reasonable request I was still annoyed he’d asked in the first place, so I said “sorry but Grandma and Grandpa need me to help clean up their house after the reunion, since there’ll be over 20 people there they’ll need a hand getting everything cleaned up.†As expected he tried to play the “family card†but I reminded him that Mom and Grandma are family too (gasp.. no way!) and that I owe them a hell of a lot more than I owe him. Petty, I know, but I’m feeling like he deserved it. He still hasn’t replied to that so he’s probably pretty salty. Oh well! Thanks for the help everyone!
TL;DR not driving my brother. My mom and I are going to have a spa day instead!
EDIT: After reading some of the comments on this update I just thought I'd add: this is a temporary solution to a bigger problem. If it ever happens again I will have no problem telling him just what I think of his requests, especially after my grandma revealed he's been doing this to my parents for most of his adult life. However, I hope you all will trust me when I say that given his notorious temper tantrums and the fact that neither us nor our parents have seen our relatives in nearly 15 years, I truly believe this was the best way to go about it. All my relatives aside from my parents, brother and grandparents live overseas in our home country, and in a way we are the "stars" of this reunion. It would be unfortunate for them to fly nearly 20 hours into our town and see nothing but tension amongst us when it is supposed to be a time of happiness. I am fully aware that I am not responsible for keeping the peace. If it was a simple visit and there was no reunion I'd have more than a few choice words for him. But this way, I don't have to oblige his ridiculous request, he will not be sulking throughout the reunion, and the issue can be dealt with more suitably and at a better time if (when?) it arises again. If I'd said what I wanted to say to him, I'd have one sulky brother and possibly a ruined reunion. Plus, my mom wouldn't have her spa day! My only "loss" is that he may ask again, which might not actually be a loss since I'll get to give him a piece of my mind if he is clueless enough to do so. I am not going to let my brother get away with being a jerk but I am not going to let him ruin the reunion, either. In my mind I compare this to putting the real issue aside until it will not affect the only time my parents and I have had with my relatives in 15 years. Thank you everyone for your input!
EDIT 2: Despite the people telling me I need to grow a backbone, most of you have been incredibly supportive of what I chose to do and I just wanted to say I am so thankful for those of you who are, or at least have tried, to be understanding of my predicament. In my previous post, I mentioned I was raised to put family first. What I did in this situation is how I interpret that, rather than giving in to my brother's demands. You guys are awesome, I wish I could give you all gold :)
