I'm flying Luton Airport this Saturday. What's the best way to travel
there from east London? My local stations are West Ham, Plaistow and
Canning Town.

Take the Hammersmith and City line to Farringdon or King's Cross-St.
Pancras and change to Thameslink (or Midland Mainline, but Thameslink
is more frequent). Fairly obviously, get off at Luton Airport Parkway.
