Data points
When Cap 1 first came out with the Venture X card in 2021 we got a bunch of miles and point together in 1 account and tried to get an EK F class award for a family
We tried to send 500k to EK - no mile at the other end.
Called capital One - it will take 2 days
Then got a call from Fraud detect unit - asked for my license etc to be uploaded
In the meantime the seats disappeared, so I ased them to cancel the transfer - sorry - can't be done!
I gave up and transferred Amex to Aeroplan and booked through AC
1 week later, the 500k reappeared in my account!!

Now - 2 yrs and many MANY airline transfers of 100k later - including a 87k to EK a week ago for a C from Eu to DXB - I tried again

Background
My friend flew to India on EY on the 9th - EY 130 got mechanical and she got back at 1 AM
Rather than call me to rebook an award, she chose to get a ticket on EK thinking miles can get upgrades
The outbound was within 6hrs, so upgrades not possible from IAD to DXB, but from DXB to DEL = about 60k was done
At least I thought for the return I could try to get the whole one done = 140k approx to upgrade - outrageous but had to be done
So I tried 200k to EK last night - same account numbers - and did not get the email at once

This am at work I saw an email from Cap 1 - fraud unit asking me to call; I tried login - unable to login - 800 number for fraud
Another upload of license and info - told all ok; but when I log in to EK - no miles and when I tried to log in to Cap1 - still locked
Another call to Fraud and then to Rewards - another agent - tells me it always takes 2 days - lie
Then my account gets locked for too many attempts
Now I am on friend terms with Fraud - finally get it open

Still no miles - I sent another 1k miles as a test from Cap1- no miles
Finally I gave in and used my Amex - 1 stop done
I get 2 miles / $ spend on C1 instead of 1 - but at times you pay the price in aggravation
