The company also announced a final dividend of 33.6 pence per share, compared with 30.5 pence per share the year before.
Group profit before tax rose seven per cent from £131m previous year to £140m for the 12 months to August 2017.
The company recorded overall sales growth of 2pc to £1.2bn for the year to August 31, driven by a 9pc boost in its travel business, which helped to offset a 5pc drop in high street stores.
For the firm's 225th anniversary year it fittingly opened its 225th worldwide store, and now has 233 open in total.
"While the economic environment remains uncertain, we are well positioned for the current year and beyond".
WH Smith said it is targeting a further £9mln of cost savings for the next financial year.
Hyett said the results marked a "important milestone" for WH Smith as travel becomes a major contributor to group performance and expects the trend to continue.
He said the group had never been "overly obsessed with sales" at the high street division, instead focusing on keeping a lid on costs, growing margins and making best use of space.
Annual profits at WH Smith rose 7 per cent thanks to strong growth at its airport and train outlets.
"It's a very different strategy in the high street business compared with travel - just because travel has overtaken it, that doesn't signal a change in strategy for the high street".
This has come as the travel chain has grown consistently - boosted most recently by surging numbers of foreign travellers looking to take advantage of the weak pound, as well as rising numbers of United Kingdom passengers.
At home, travel business sales over the summer benefited from a sharp rise in the number of overseas visitors coming to Britain. This represents more than 60 per cent of the group's trading profits and includes £9 million from its growing worldwide travel business.
