Also, my flight was delayed twice and cancelled once while every other airline was on time. The plane had problems. I couldnt get any answers about the baggage allowance. YOU ARE ALLOWED 2 BAGS CHECKED AND 1 CARRY ON FREE WITH DELTA TO EL SALVADOR. Ignore whatever new rules say, they are hard to read but the above is true for El Salvador as of Feb 2010 and forward. They have to be 50 lbs or less checked and 40 for carry on.
DO NOT FLY DELTA IF YOU HAVE A ONE WAY TICKET. They will check for ongoing travel. Immigration in El Salvador never does, TACA won't but DELTA does. So avoid Delta, fly TACA if you only want to buy a one way ticket. I ended up just printing a professional itenarary from TACA and it worked but barely. So avoid DELTA.
