We require the same four items for airfare that we require from every other receipt: who you paid, how you paid, what you paid, and when you paid. Some booking confirmations don't include this information, so it's important to make sure you are submitting the right items.
Booking direct
Attached is a receipt for a Delta flight. This is the best possible version of the receipt as it clearly lays out all of the information we need. You can get it by going to your Delta account. We highlighted the parts we need and explained them, so you can look at any other type of receipt you might submit to check and make sure it has the same information.
Discounts and extra benefits available through CTP
We encourage you to try booking through Collegiate Travel Planners (CTP), the University's travel booking partner, if you are a University employee. It has special negotiated rates with major airlines and the receipts are automatically saved to your U-M account so you can't lose them. It also has special benefits like priority boarding or complimentary premium seat selection on some airlines. You can use CTP for business, org, or personal travel. Find out more here.
If you book through CTP, the receipt you get directly from them in Lightning is the one you should submit, because it includes the small fee charged by the travel agency to cover the costs, and this fee is reimbursable.
Be careful with fare aggregators
Use caution when booking flights through aggregators like Expedia or Kayak. These often take payments directly through the website and transfer the payment to the airline, leaving the airline with no receipt to give you because you made no payment, and the website's receipt not being sufficient. It's best to book directly with the airline, or through Concur.
