I must have good karma working with me.
Had close to 60 flights on Taca when they flew out of Miami to Belize and never had a lost bag or luggage that did not arrive with us.
Have about twenty with AA out of Miami.
They have gotten better the last year or so about leaving you sitting out on the runway waiting for a gate to become available. Haven't had any luggage issues with them either.

AA is having a $350 deal out of Miami to Belize showing up on Travelocity this morning.

I just booked a good four legged trip on AA from BZE through DFW then traveling in the Northwest for US $735 including tax. Coming back in Sept. I had to book on a Saturday but that was OK with me.

Per some of your suggestions I checked on TACA going through San Salvador to SFO - It was more than I paid for all of the AA travel.

Scuba, most don't have such a complicated schedule such as yours..I still reccdomend Continiental, even if I can't spell it at times..

Lacy - Most don't have such a complicated life either. LOL But as one of my favorite books says, "Our troubles, we think, are of our own making." At least I'm not bored.
Being a fat lady I appreciate the extra room on AA. Thank goodness we don't all like the same thing at the same time.
