Getting to Heathrow for an early morning flight

Thank you, Emma-- that's a great point about negative reviews.

We have used suntransfers.com in many cities in Europe and always found them reliable - at any time of day or night.
Pricing is usually competetive.

Thank you, Joni-- I'll check them out!

I would arrange a shuttle through the hotel - if the hotel does the booking it gives the company more incentive to be reliable than if it's a random visitor who may never return.

Just Airports has been fabulous for us. We have used them 3 times. We had four people and a wheelchair and they picked us up in a van, on time, and very nice driver. I would use them again. My sister used them too, no problems. They can call you on a cell if there is any problem. We had them pick us up at Hertz near Heathrow and I was worried about us being in the right area, the guy called and said he would be there in 5 min and was a few minutes early. They are great!

The Night Bus N9 is the adventurous and cheap way of getting there but for a group of 5 probably not for the best!

MrsEB-- thank you for the suggestion, I'll check them out!

Philip-- we'll be staying in a flat, otherwise that would be my first and only solution. Thanks!

Susan and Monte-- another for Just Airports! Thank you for your reassurance.

Marco-- I'm generally up for adventure, but NEVER when I have a plane to catch! Thank you!

We (family of 3) needed to get to Heathrow early on a Saturday - we had the hotel book a taxi for us - rate was reasonable and no traffic worries that time of morning.
