This was interesting.

Booked a Flex return ticket for my sister and her kids (in Y). They are coming to Singapore over these school holidays. I then needed to push the outbound flight out by one day as my sister changes her mind more than Amelda Marcos at a shoe sale.

Anyway, thought than rather than send an email to my local EK office, I would try the whole "you can manage this all online" feature.

So I pulled up the booking, changed the date by one day and the system says I owe them some paltry fee. Which I pay via credit card. All seems to work just fine.

Then I go into the booking a few hours later as I managed to find 3 x J seats for their return flight home. Login into MYB again, click upgrade, then the system tells me I owe it 37,500 miles per person for the upgrade (and not the 30,000 miles I should have) given that the fare was Flex both ways when originally booked.

Here's the glitch.

When you go into manage your booking online, (like do a date change), the system refares the ticket to the cheapest possible (in this case, Saver). But it doesnt tell you its doing this. You find out the hard way.

After a lot of arm waving - the local EK office sorted it out. And put it back to Flex. Its a big difference - because the difference in miles across the 3 tickets was 22,500 (or US$900 if you had to pay for them)

So be warned. If you go into change a booking online - your Flex ticket could very well become a Saver. In the blink of an eye. That means half the miles earned (tier and Skywards) and a lot more miles required to upgrade.

I will let you know when the glitch is resolved...
