Inability to online book a trip when flying into one city and returning from another

Through the years, I have successfully booked numerous vacations ( for my family + wife and myself ) using the Expedia AARP Travel Center website. As I once started to book our January Costa Rica vacation, I immediately noticed the website had been updated. However, I was unable to book a flight going into San Jose ( SJO ) and approx. 1 week later, leave from Liberia ( Lib ). After numerous failure attempts ( trying different prompts, etc. ), I called the national travel number. The gentleman who I talked with confirmed that this ability has been removed for AARP customer but he could assist me ...and perform this task at his desk. Because I did not have any desire to stay on the phone for hours
( examining different days, times of departure from both cities, etc. ), I thanked him for this information... hung up the phone.
Additionally, I use to be able to reserve multiple hotels in the various cities/ towns the vacation encompassed. Apparently, that ability has also been removed.
All I can say is that I don't understand why such a useful tool would have been deleted...Eventually, I booked my air flights through the airlines but did individually reserve the hotels through the AARP site.
