Having read US Amex and its competitors transfer instantly to Flying Blue, I called Amex Finland on Thursday to verify the website information "5 business days" for all programs. I was told transfer time for all programs is 5 biz days. So I decided to test it out. I instigated a transfer to not only Finnair and Flying Blue, but also BA, SAS and Delta. Here's what happened.
Transfers executed on the self-service portal on Thursday just before 5pm.
- Delta: instant transfer
- SAS: next day around noon (Friday)
- Finnair: two days (Saturday)
- BA: two days (Saturday)
- Flying Blue: two days (Saturday)
