I wonder will cash fees go up also:

Rebooking via hotline: 4,000 AM or US$40, so revised 5,500 AM or US$55 (charged as HK$429)
Refund: 12,000 AM or US$120, so revised 15,000 AM or US$150 (charged as HK$1,170)

Rebooking via online: 1,000 AM or US$25, so cash fee gets a smaller bump to US$50 (charged as HK$390)
