TRAVELLERS who accompanied Princess Diana on her flight to Hong Kong yesterday shared one thought - that their mums and dads would have been more excited than they were about their brush with royalty. 'I'm sure my mum will be thrilled when I tell her that I could have seen the Princess of Wales if I'd looked out of the window,' said Cathy Belletty, who did not realise how close she had been to the special Upper Class passenger until she was told by the South China Morning Post. 'They told us some officials had to meet someone off the plane and I thought 'Oh no, maybe they're going to search someone for drugs or something',' she said. 'Maybe that's why we had to get on at Heathrow so early, and then we sat on the tarmac for ages with everyone in their seats while the Princess of Wales got on,' she said. Liz Dobson, returning to her Lamma home after a holiday in Britain, said she recognised the princess when she caught a glimpse of her head as she walked down the steps. 'I thought, 'You haven't just travelled for 12 hours in economy with two kids by yourself - like me',' she said. The royal traveller on the Virgin Dragon Lady 747 had kept a low profile in the exclusive section, unnoticed by those in the economy seats, passengers said. Perhaps she was enjoying the perks of a personal massage and aromatherapeutic facial offered by an in-flight beautician to all Upper Class passengers in return for the GBP2,013 (HK$25,000) fare - paid by herself, according to a Virgin spokesman. But one passenger said: 'I would be interested to know whether she played the Nintendo games or the casino games' - or whether she shared the special no-armrest 'love-seat' in the Upper Class lounge with any of her seven-member entourage. Last night, the princess dined at The Peninsula in aid of the Leprosy Mission. Today she will visit Eastern Hospital followed by Youth Outreach, a refuge for runaways, next door. Dinner will be at the China Club in aid of the Cancer Fund. Tomorrow, she will visit the Shek Kwu Chau drug rehabilitation centre and fit in the Salem Open finals and tea with the Pattens before returning to London.
