I got this card in 2011 on the 100k bonus. Canceled a year later on the annual fee. Applied early Aug for this offer w/the same ffn, address, etc.. Approved. Used those handy CGC's, statement posted yesterday and 52,500 Avios posted to my account this morning. If you got this card in 2011 and haven't churned it again since, get in while there's no annual fee, water is warm!
