If you liked AA business class, you'll love BA business class!! Our beds are properly flat and you don't pay for drinks in the lounge ....!

World Traveller Plus fares are often heavily discounted US-UK, so at the right time you can probably get a ticket for about $600-800 and then use 25,000 miles to upgrade at the time of booking to Club World. You'll get back around 10,000 miles for the flight (standard WT+ miles awarded) so the net cost is only 15k per person.
