A 45 min. connection sounds tight and even risky, but thankfully SAL is a small and compact airport so this worked very well.
The AV Lounge is a huge improvement over the former TA lounge. It's well designed with smart use of space and the catering is decent, although dishes should be replenished more frequently from my experience. I did not see any hard liquor except for beer in the refrigerator. My visit was in the the morning and for a very short time so perhaps liquor is brought later during the day.
FA's were friendly and smiling. I appreciate that I was addressed by name. Catering was solid for a flight of this length.
