American Airlines, yet again, cannot seem to get its equipment operations and flight departure times aligned. Another 2 hour delay due to "equipment maintenance" - the flight departure was 4:55pm and there is still not jet at the gate. AA OPS had ALL DAY to plan for the equipment that will ultimately arrive at the gate, however, without having been cleaned, per the announcement by the gate agent, adding to yet another delay. Moreover, AA cannot be upfront about the delay times - they put out delay, after delay, after delay - American Airlines needs to be honest about expected timeframes. I can no longer recommend AA out of LAX. As a frequent traveler and a First Class passenger I recommend NOT flying out of LAX on American Airlines.
