Then either plan your journey better or suffer the cost 
You live near enough to be able to leave once you have a confirmed landing time... aim to arrive as the plane touches down and you'll never pay more than an hour 
True but the amount of time it takes to hand over the plane to ground staff, as well as the transfer from airside to the front of the terminal varies a lot. I try to time it perfectly because you do not want to p-off a jet-lagged, pre-menopausal woman who has been awake for 18 hours and standing on her feet for most of it. Sometimes she is delayed and I have to literally circle the block, which if you know heathrow can be a pig.
A big difference between working on a plane and sitting in one... Sure she appreciates being met with her favourite Starbucks and a hug followed by a stroll to the car in the car park rather than trying to find you on the forecourt 
Nope. Kid gloves until she has had a sleep. We have a mutually agreed protocol for the days she comes until after she has slept:
- Clean house
- Clean car
- If a West coast trip she will be very hungry, so have a traditional Hawaiian meal ready (fried spam, eggs and rice earns a lot of kudos)
- No important conversations that require decisions, hold them until later
- Any conversations regarding dates/plans that do occur must be repeated after the sleep as she will forget them (this caused a lot of issues when we first got married before we knew)
If I am late anything wrong gets amplified on a logarithmic scale depending on the the amount time she is waiting and factoring the weather variable in to the equation.
After the sleep she is back to normal, but beforehand........
