Arriving at Heathrow and traveling to London Easton on 12/24

You had quite a few answers to this question in your post a month ago. Little has changed.

You still can't take anything into Paddington including Heathrow Express.

You could still take a taxi or minicab, as discussed.

There is no strike scheduled for the Piccadilly Line so you could do that.

Did we miss something last time around?

It is important to keep your question about this in one place, so people do not repeat or contradict what has already been suggested. For example, some might offer the Heathrow Express as a solution, but if they had seen your other thread they would know that is not possible on Dec. 24.

Thanks - the news re Gatwick had me concerned about Heathrow, as well as, impending strike talks.
