I’m a DL retiree and have not traveled international in many years. I’m now planning a trip. I looked at Travelnet to search out flights. Some of the flights are KLM codeshares (KLM metal all the way). One flight is DL/KLM (DL to europe and KLM to final destination).
I’m unable to book the flights using Travelnet; even the flt that is DL to europe/KLM to final destination. I thought DL retirees could travel for free on codeshare flights. Why am I unable to book these flights? TIA for any information you can share.
