I suppose it depends on the individual, how far ahead he or she books and the time of day the trip takes place.
It was ‘canucklad’ who decided to try BA and Little Red in preference to East Coast for Edinburgh-London-Edinburgh as the fare was lower than East Coast’s £126 flexible saver return in standard class.
Marcus secured a good rate for his trip by booking two weeks ahead.
If he were to book today for travel next Tuesday/Wednesday the fare (out 2nd, back 1st) would be not far off £200 return each.
In fact at short notice it would pay to book the £229 return Scottish Executive fare which provides 1st class both ways. The outward must be booked before 1800 the day before travel but the return can be open-dated. This is a fixed price ticket.
