Fares are likely to be lowest on the latter two airlines. You can also fly non-stop from Aberdeen, Belfast, Bristol, Bournemouth, Cardiff, East Midlands, Glasgow, Jersey, Kirkwall, Norwich, Shetland, Manchester, Southampton and Wick. Most of these, though, are commensurately high.
Trains are more reliably affordable. From London, GNER (0345 225225) has a return fare of pounds 20 if you book through its website, www gner.co.uk. Good first-class fares from GNER services are available if you book in advance. The best bargain is the After Eight summer special on GNER: pounds 12 single and pounds 20 return for any journey on GNER between 8pm-2am, Mon- Fri. Scotrail (0345 550033) has deals on sleepers from London Euston. Virgin Trains (0345 222333) also has good prices.
