Way back in November I booked with KLM in PE. It was a direct flight from IAH (Houston). I few weeks after booking I received an email from KLM informing me that I had been involuntarily downgraded from PE to economy. KLM and Delta share bookings and I called and asked if I could be involuntarily upgraded to BC? Of course the respond was no but that I could change my flight to Delta departing from DFW. There is about a three hour layover in DTW but DFW is a little closer to us and the departure and arrival times were better. Point is, you never know what to expect when you travel. It is an adventure. Just waiting for Delta to change flight times, equipment, etc. Haha
