American Airlines uses Terminal 3.

Unless you have a really good reason for taking the HEX, all you'll get for saving a few minutes is a big dent in your wallet. If you're staying at a hotel somewhere else in central London, taking the HEX and then either the Tube or a taxi to that hotel will save you about 15 minutes over taking the Tube all the way. (It takes time to make those connections.)

Thanks Tim.

I was going to use the HEX only because we have purchased 4day BritRailFlex passes.

I will reconsider HEX based on your email.

We're using the Heathrow Express as we got two free round trip coupons with our London Plue Passes.

You're welcome, Jim.

If you want to have an "extra" day on your flexipass for a day trip outside London, then for sure don't use a pass day just to take the HEX.

We're going to use the London Plus pass, also, with the free HEX passes. Does the 4-day flexi-pass not include those?

Heathrow, Gatwick, and Stansted Express trains are covered by BritRail Consecutive and Flexi, BritRail England, and BritRail Plus Ireland passes (starts use of a travel day). The London Plus pass includes two separate vouchers for airport trains.
