My Brother has just booked a trip using miles, LON~MCO Virgin Upper then Vegas back to London BA 1st class (quoted $14,000 if not using miles) just cosing him taxes and internal flight between MCO and Vegas.
Thanks Wayne! I thought I had to pay cash for economy ticket and then upgrade but it was using miles. So I worked it out that it was cheaper to do that than get a companion seat (couldn't combine them sadly) as the PE ticket would have cost £600 more! So I have two PE returns for a grand total of £1300. Not too bad really.
When I was looking at an upgrade with points you had to buy one of the full price economy tickets to qualify - couldn't do it from the cheaper economy fares
Worked out better value to go for a PE flight using M+M
mine was buying the economy on points then free upgrade to PE. All thanks to Virgin CC. Happy with end result - and very happy to be heading back to WDW next Jan!
