Four checks seven days before you fly catch almost every airport parking problem that would otherwise happen at a barrier at five in the morning.
Parking is usually booked weeks or months ahead. A great deal can change in between, and none of it announces itself.
One: check your terminal
At multi-terminal airports this is the commonest error and the easiest to catch. Heathrow and Gatwick have car parks that are genuinely separate places.
Airlines move between terminals more often than passengers expect, particularly at the seasonal schedule change in spring and autumn. A booking made in March may name the wrong terminal by August.
Check the airline app rather than your memory of the original confirmation.
Two: check the registration
UK airport barriers read number plates and match them to your booking. If the plate does not match, the barrier does not lift.
Things that break the match in the weeks before a trip:
A courtesy car while yours is being serviced
A hire car taken for the drive down
Borrowing a relative's vehicle because it fits the luggage
Changing car entirely since booking
Changing it is normally free and takes a minute on the phone. Doing it a week out is easy; doing it at the barrier is not.
The booking is attached to a number plate, not to you. A week before is when you find out whether they still match.
Three: check the dates
Specifically the return date, which is the most expensive error on any parking booking.
Two things to verify. Whether the return flight lands after midnight, which puts the car leaving on the next calendar day. And whether what you called "a week" is actually eight days once both ends are counted.
Overstay charges are higher than booked days and sometimes charged hourly. A week out, this costs a phone call; on the day it costs money.
Four: check the operator is contactable
Ring the number on the confirmation, or at least save it to your contacts.
You will want it at precisely the moment your email will not load — a delayed flight, a barrier that will not read, a car that will not start. A confirmation with only a web form is worth knowing about now rather than then.
While you are there, screenshot the confirmation. Signal at car park entrances is frequently poor and a screenshot works offline.
Is this the moment to rebook?
If you booked a flexible rate, a week out is a sensible point to check whether anything better has appeared.
Prices generally rise as the date approaches, so this rarely pays. It occasionally does in the quiet months, where an operator with unsold space has discounted.
Two minutes to check, and no obligation. The flexible rate you paid a small premium for is precisely what makes this possible.
What if your plans have changed?
A week out is comfortably inside most cancellation and amendment windows. That is usually 24 or 48 hours, so you have room.
Amend rather than cancel and rebook where the trip is simply moving. Amending means paying any price difference; cancelling and rebooking can mean losing the original payment and paying a later-booking price.
What about the car itself?
Five minutes in the driveway, which is impossible once you are at the airport:
Check tyre pressures, since they drop while standing and more so in cold weather
Consider the battery's age if it is over about five years and you are away a fortnight
Leave a scraper in the car between November and March
Check nothing is propped open, including boot and glovebox lights
Fill up on a normal route, not on the airport approach
What about the route?
Check it the evening before rather than a week out, because roadworks change.
Overnight closures are common and a diversion at four in the morning with no traffic to follow is genuinely disorienting. The week-before job is to know whether the route carries tolls or clean air zone charges; the night-before job is to check it is open.
The whole list
Seven days out — terminal, registration, dates, operator phone number
Two days out — tyres, battery, scraper, nothing left on
The night before — route check, fuel, screenshot the booking, load the car
Ten minutes spread across a week, and almost nothing on this list can go wrong on the day. Compare and book early at Manchester, Birmingham or Stansted, then let this routine do the rest.
