DH is booking flights for portugal and there is a choice of 11.20 am or 6.10pm return. DS is approaching one year. Will he sleep on plane if we get later flight (arriving back in house by 10.30pm ) and pop him straight to bed? We are flying out t portugal at 4.30pm so are lsing our 1st day, so i want to maximise our week's stay. what does anyone advise?
