That is one of the most expensive times of the year to fly. Any prices on Delta are over $2000. How many miles do you need? If it is less than 10,000 MQM it may be less expensive to get a credit card if you can get the spend in before the end of the year. There is Delta Reserve card that costs about $475. Check Rene’s Points which is a blog but you don’t have much time. If you have any questions let me know.
Blessings and Happy Travels. Get your Flu shot!
