Good to know. I was curious/trying to remember the specific terms (specifically if/how it applies to reward flights since I have one coming up), and here they are just for reference:
Free First Checked Bag: When you use your Card to book travel directly from Virgin America (or to pay for taxes and fees for reward tickets), you are eligible to receive a statement credit for the cost of checking one bag each for you and a companion traveling on the same reservation on Virgin America marketed and operated flights (codeshare flights with a Virgin America flight number but operated by another airline are not eligible). You must include your Elevate account number in your reservation and your Card Account must be open and not in default at the time of reimbursement. The bag fee will be charged and then reimbursed to you in the form of a statement credit 6 to 8 weeks after completing travel. If you are already eligible to receive free checked bag allowance(s) or fee waivers, you will not receive additional free checked bags. The free first checked bag benefit cannot be combined with any existing Elevate Gold or Elevate Silver program benefits, including any waiver of baggage charges, or combined with any cabin-specific inclusive baggage allowances for you or your travel companion. Checked bags must meet weight and size restrictions as detailed at virginamerica.com; additional fees for additional, overweight or oversized bags may apply.
