have a 9 am flight out of Heathrow T2 - worried Tube won't get us there in time on a Saturday morning for an international flight check in - anyone know about how much a cab would be to go to Heathrow?
Google Taxi FareFinder London and you can estimate cost. I'm taking Heathrow Express myself when there this August . You can print your tickets out ahead of time. More expensive then connect but to me worth extra cost .

Book a car service, cheaper than a black cab:

Look at the later pages for more recent recommendations. Blackberry Cars are very popular on TA.

I have used it to get an idea of approximate cab fares
You can get discounts on the Heathrow Express by booking online in advance, but if the OP is starting from Kings Cross and not Paddington, I wouldn't think the HEX would save any time, which is his or her concern.
As advised, a pre-booked car service will be less expensive than a black cab. If you want to go by road, I would pre-book a car service and save money over a taxi.
You don't mention how many people or what day of the week you are traveling. Checking Just Airports(www.justairports.com) from St Pancras to Heathrow for a Saturday morning 5 am pickup, fares as low as £28. Our daughter used them in January and liked the service. We'll be using them in June.
Awesome info - thanks everyone! Sounds like the car service is the way to go.
