I sent an email via Barclays customer service on their website requesting an upgrade from the Red Aviator to the Silver Aviator. I explained the reasoning behind my request mentioning specific points and benefits that the Silver card has over the Red card. I'm keeping my fingers crossed but honestly don't expect a positive result since they seem to still be in transition. Hopefully they see all the times I have requested the upgrade to Silver and hope that "the squeaky wheel get the oil"!
