ANA only cost 3,000 miles to cancel.
You can book *a partners directly on ANA's website unlike SQ.
How much does a change cost?
And that's another major issue I forgot to write before.
I book a lot with Singapore with a stop in Europe and closer to the flight I have found many times United open and I change for just $20
Ana doesn't allow changes 3 days before flight and that's when United opens availability.And for a change you need to call in and they are not open 24/7
So you could miss the United direct even if it opens.
