There is definitely something going on. I had planned flights from BHX-DUB-BHX September 2024. Availability was showing as 5 seats per flight on every flight throughout the day. Tried to book last week and whilst payment went through the avios didn’t and booking failed. Tried to book this morning and availability is only on the last flight of each day in question, with 8 seats on this flights. This is absolutely no use for me. Our flight gets in at 1000 from ORD. I really didn’t want to have to wait until 1900 for the last leg
