It won't show me how much it costs for an economy to business upgrade.
Are you selecting an upgrade option on the advanced search page
If you select rpu/gpu it doesn't matter as there are no fare class restrictions for PS flights, only R availability
If you select Miles/money - then it should give you the miles and copay in the second column
Make sure you select buy economy and upgrade to business
