Review of LACSA flight from San Salvador to San José in Business

This flight was sold as LACSA and code shared with TACA, but the actual plane said TACA. The cabin was different from my previous flight and this is an issue that I noticed on all of my TA flights. They don't have a consistent cabin. I felt that for all the four flights that I took with them, I must have been in a different cabin each time.
The purser on this flight was very professional and greeted everyone cheerfully. The load was full in J and most pax were businessmen flying between TA two main hubs. A tray with pre-departure drinks was distributed (orange juice or water) and coats were taken.

The very professional FA

For such a short flight, there was a breakfast service consisting of a mini quiche, some fruits, a slice of processed cheese and turkey, warm muffin, a croissant like roll, jam and butter. Service was done from a cart and here is another peculiar thing flying on TA J - they use plastic tumblers in front. Yep, no glasses at all. I think this is the only carrier that does not use glasses in a premium cabin. Come to think of it, it makes sense since they don't have to add extra weight to the galley. Maybe the savings in fuel is not that minimal after all. I always look for different types of juices or soft drinks when I fly on a foreign carrier (I'm tired of the oj, tomato and apple juice trio so prevalent on US flights). Thankfully TA offers a strawberry/banana nectar that I enjoyed very much.
