After a month of fruitless searching for a normal trip (without a nite at the Baltimore airport) with United to Roatan our back up hope is OAX from ORD. There appears to be lots of flights at 24,000K. Before I call the knowledgeable Delta rep do they convert K to miles for redemption or does K=a mile? 24,000K should equel about 14,400 miles (I think). Also since AeroMexico does 1 way awards; will that be a problem for Delta to book? If you have done this please forgive my ignorance and walk me thru it. Thanks
