I think you will find it quite easy and if you just go with the same routine but in the new time zone, you will proabably find that your baby adjusts quickly.
We live in Hong Kong and came back to the UK when our dd was 4 months old. (8 hour time difference.) She slept most of the (night) flight but did wake up at normal wake up time. We just let her sleep when she got tired but tried to stick to the rountine as much as possible. She went to bed at 7pm as normal the first night but woke up in the middle of the night for couple of hours. I just got her up at 7am as normal, and the next day she was fine and back on schedule.
When we flew home at the end of the trip, she was waking up in the middle of the night screaming at about 1am (first 2 nights) and when we tried feeding her, it turned out she was hungry. (personally, I always find I'm hungry at odd hours when I have jet lag.) But after being fed, she went straight back to sleep for rest of night.
We'd only just given up the 10.30pm while we were on holiday, so we just went back to waking her for a few days until she was properly back into the routine, and then dropped it again. To be honest, think she adjusted better than us.
HTH, good luck with the trip. (BTW, if she is older, I'd be interested in your feedback. I plan a trip home when she is a year, so wonder if things will be so straight forward then. Particularly trying to get her to sleep on the flight...)
