My question arises because I booked a retrurn trip to Stuttgart, Germany to visit a friend. My dates are from the 7th of July to the 22nd of the same month. Soon after booking a non-refundable, non-changeable ticket, my friend tells me she can only have me in her house till the 14th.
Well I moved mountains and oceans trying to find a solution for this issue. My return trip included a connection in LHR so I came up with the idea of calling the airline and asking if my flight from STR to LHR could be moved up to the 14th and spending some time in my favorite city before catching my flight back to SEA from LHR on the 22nd. Simply put: just change one sector of my itinerary; an eight-day lay-over.
The airline said this would cost me over $900!!!! I know! I almost collapsed.
Well then I said, I'll just buy a return ticket from STR to LHR on the 14th and returning on the 22nd to catch my original flight back home on that same day. This was a cheaper option at $127. However I came up with an even cheaper option. And hence my question arises:
What if I bought a one-way to LHR from STR on the 14th, skip my flight on the 22nd from STR to LHR and just catch my LHR-SEA on the 22nd and go on home? Can I do it? Can I just check in online with NW without checking in for my BA STR-LHR? I am not looking for them to give me a voucher or refund for "missing" that flight (although that would be nice) but it is a much better option and much cheaper at just $56. Will I be questioned about this by the airline's employees in LHR or even worse, when entering the UK will Customs and Immigration ask why I have a one-way ticket and not let me in?
Any input is greatly appreciated and thanks for all your help.
Peace in the Middle East!
