booked yul - sfo - mel in economy for 60k ac a few weeks ago [1st leg ac metal, 2nd ua]
last week the ac leg opened up lowest saver price for j, so upgraded to 87.5 with 1st leg in business with hope of getting 2nd leg later on..changed on website was not charged change fee since kept the same flight
the ua leg now opened in business, the website showed the option to get both legs now in business [only since i already had it. a new booking would be 166k]. but couldnt process it. i called in and the upgraded and waived the change fee after i explained to them that the 1st time they didnt charge me...
so yul - sfo - mel in j for 87k
