The UK's top two listed travel companies. Thomas Cook and TUI Travel are set to bring out trading updates, and both face much the same problems: rising oil prices, political uncertainty in some popular travel destinations and consumer concern about whether the budget will stretch to a holiday this year.Thomas Cook noted in its first quarter statement that the political unrest in Tunisia and Egypt would have an impact on the following quarter's profits of around £20m. TUI Travel, the operator of brands such as Thomson and First Choice, said in early February that the problems in North Africa could hit results for the current quarter by £25m to £30m. Repatriation and cancellation costs in Tunisia are estimated to have cost £5m.The steady stream of retailers' results will continue with the likes of Mothercare, Topps Tiles and Domino's Pizza.Peel Hunt thinks Mothercare should report a notable improvement in its fourth quarter UK sales "with a weak snow comparative and the benefits of January stock clearance"."We are leaving our full-year profit before tax expectations unchanged at £32.5m; they sit c5-7% below consensus. We had taken a dim view of the sales environment over the first quarter of 2011 and forecast only a two percentage point improvement in quarter on quarter sales performance," Peel Hunt said.
