A SPECIAL rate offered last year on Qantas Airways to London is being reintroduced on a selective basis. Peak season departures on July 3, 5 and 10 are being offered at $6,900 (children for $4,650) round trip including a car for one week. The catches are there must be two adults (so $13,800); and the Qantas flights to London operate (nonstop) from Bangkok, so you must take the Qantas flight from Kai Tak, which leaves at 5.50 pm, with a transit time in Bangkok of 31/2 hours. You can return when you like. Contact Wallem Travel, phone 821-3868. THE Sukhothai hotel in Bangkok has further discounted its suites rate until the end of September.
