HONG KONG, May 3 (Reuters Breakingviews) - Chinese travellers are opening their suitcases again, but not their wallets. Domestic travel bookings during the holiday surged eightfold from a year earlier, surpassing pre-pandemic levels, according to online travel agency Trip.com (9961.HK). The return of Chinese holiday-goers should be a huge relief at home and abroad. Before the pandemic, domestic tourism contributed a whopping 11% of GDP and 10% of national employment, according to Fitch. The country's Big 3 carriers - Air China (601111.SS), China Southern (600029.SS), and China Eastern (600115.SS) - are grappling with high oil prices, a weak yuan and geopolitical tensions.
