We did a rough itinerary and booked fully cancellable hotels via the Hilton website. Submitted everything with a paper saying what we were going to visit in each place. This was advised by an Embassy employee. 1 day later we have our 60 day visa.
so will the extra 30 days be valid until 60 days plus 30 days after entry, or do we have to be out by the 1st, which is the date the visa says its valid until?
If the fare is cheap, go for it. I flew them many times on their old LHR to NYC as it was the cheapest First Class product across the Atlantic. If you expect nothing, you will be happy. I used to fly FC for the same price as BA economy. On that basis, the old enormous seats were great. The food delivered on a trolley from which you could choose was great. The baggage allowance was great. The price was extraordinary. BUT I never flew via Kuwait and never had a plane that went tech. Every flight was delayed by an hour or so, but at the crazy prices I used to pay, I put up with it.
