Thanks for the welcome Ralph, and thanks for the congratulations jplus!
Ralph's right, the flights will generally be Lebanon<->London.
Since my company is only involved with accommodation, flights are something out of our field, so I can't ask them for support. I'm actually one of the top people in the company so I could definitely make things happen in this area... And I understand that agencies & employees of certain organizations qualify for ridiculously discounted flights... Which would turn the $500-1000 burden into $50-150, which is quite manageable. Is this a possibility for me or a pipe dream??
My nationality is New Zealand, and since I work in the travel industry my passport is really full & officials (even on the UK border which is one of the most stringent I've encountered) are generally quite co-operative, even if they ask me a bunch of questions.
Looking forward to hearing your thoughts!
Alex
