Just had a reply from United telling me they will offer the 90 day status match challange for my Krisflyer Gold to Executive Premier and my wifes Royal Orchard Silver to Premier status, with the usual 15000 and 7500 miles rule.

Faxed them copies of our last 2 statements with a note saing we had moved from Australia to UK and most of our flying would now be between UK and USA.

We had booked a return flight on United from LHR to ASE and can now choose the Economy Plus seating on our trip.

It took about a week to get a reply via e mail from them.
