I'm seriously considering upgrading from Amex Gold to Platinum because the added perks will come in handy this year as I plan to travel a lot more. I called Amex customer services today to see if they would offer any personalised upgrade bonuses (No!). Worse still, the agent claimed there was no upgrade path and I would need to complete a brand new application for the Platinum card. I'm sure it used to be possible to upgrade between cards though... So, does anyone have any experience of the upgrade process?
