Low-risk travel tips

Fly Via Germany
Catch a Lufthansa (0870 8377747, www.lufthansa.com) "business jet"; max 50 business class passengers on transatlantic routes ex-Germany. Smaller planes are a less likely terrorist target.

Take the train
Eurostar (01233 617575, www.eurostar.com) to France and Belgium connects with high-speed trains to other European cities.

Take a Private Jet
With Net Jets (020 7590 5120) or Flexjet (020 8538 0225). Cheaper than first-class. Geneva-based Club Airways (00 41 22 735 1690), offers fractional ownership of a private jet.
