Seems I was extraordinarily lucky this weekend. Came in to IAH on N666UA that went tech before the next flight to EZE creating a 3:30 delay and returned from IAH on N673UA that had just arrived the day before from LIM after a 4 hour maintenance delay...my flights however were all unaffected by maintenance issues. Same for the remaining convoluted domestic itinerary around this...should probably have bought a lottery ticket as well:-)!
