I had a very very neat boarding process recently with H2. Gate agents early enough at gate, making clear announcement, 2 (actually 3rd for priority) lines prepared with clear signs with rows 1-14 and 15-X, where they started with a priority boarding 2 ladies checking all prioritys, then proceeding with the line of 15+ strictly. There was no hassle, people in line 1-14 neatly waited including me and plane was effectively boarded from the back.
All extras on H2 are paid. It is a LCC airplane Sky Airlines and the best so far I have experienced. Ticket was 25$ only and smily staff, courteous and punctual. While I flew LAN shorthauls and paid 30 times more expensive another ticket compared to H2, I got absolutely opposite experience and no recognition as OWE, nada. I was amazed how poor a flagship LATAM can be. They have just introduced BOB concept too, no more freebies during flight.
