SLF: Glad you like our new on-line booking tool for Explorer. We are closely looking at all feedback posted and identified to help us in refining the tool as we go forward. Whether or not this will include the ability to split the payment for a single booking between two credit cards we'll have to wait and see. But I think it is unlikely. The software powering the facility is complicated enough as it is, bearing in mind the incredible flexibility of the product offering - giving customers the capability of booking up to 16 sectors on any of up to some 9,500 flights a day covering almost 700 destinations in 150 countries... Sorry! I am sure you'll find other ways of solving this issue - perhaps, if you are getting more than one ticket, by creating separate bookings for each of them, or by making a "payment" from one of your credit card accounts to another... FTers seem to be full of ingenuity! Hope the trip is great! oneworld4u
