Successful booking on S7
Finally talked to an agent who could do it but it was difficult even for her.
If anyone is interested, try telling the agent to follow these steps:
1) the agent pulls up the award
2) then put in S7
3) cancel the award
4) at booking put in code 'E'
5) price it as award travel
The agent said this would be a difficult, roundabout way for any agent to book an S7 flight but it does work.
I do in fact have a res. on hold from Sochi to Yervan via Moscow for 10,000 AA miles and only a $25 res. fee because there are no departure taxes. What a deal!
