Bymonek,
Thank you for your answer. I have been considering Emirates for about 6 months now. I have not heard anyone mention commuting specifically before even though I have been lurking here for a long time. The ability to commute would be a great thing, as my wife is in an employment contract that we cannot afford to break and is not up for about another 2 years.
I don't know this TCAS person, but I assure you I am not he.
