This year’s London vacation is coming up, and what do you know? The RMT is
threatening to strike when one of us is flying home from Heathrow.

We are staying in Walthamstow, near Bakers Arms (Lea Bridge Road/Hoe
Street/High Road Leyton intersection)[1]. The flight is scheduled for
0950am on Thursday, June 30.

If there is no tube, how do we best get to Heathrow? I assume other
services are not affected.

Use the TfL Journey Planner and untick the Tube option.
