Using unflown e-credits
 

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.

Ecredits are just a heading. You can only use one unused eticket to pay for a trip. You can use up to three vouchers (these are what DL issues for CS purposes) at one time. Problem is DL groups them all under heading of ecredit and makes it look like your unused eticket became a ecredit, like it was converted to something else. It's the same thing as before just showing in section called ecredits.

Chat agent checked with a supervisor who told him to go ahead and do it.

Curious how they actually did the processing.

If the OP experienced significant schedule changes, a refund should have been offered.
