I have 2 e-credits from unflown flights. Cancelled after Delta schedule changes. Value $173.20 and $380.60. Trying to book new reservation from Las Vegas to Helsinki and back in December.

Delta chat agent says "You have 2 unflown flight credits. You can only use one per new reservation." I asked if it's some new rule and I'm told "Not unflown flight credits. One may have been a voucher." (They weren't.)

I just booked a trip yesterday Las Vegas to Minneapolis and back and used 2 unflown e-credits.

Guess I'll need to call Singapore later today since the e-credits aren't showing in my account. Seems like my chat agent doesn't know what's up.
