I am planning to fly with my 18mo dd next month..just the two of us. She’s an experienced traveller, my dad was very ill just after she was born so we travelled a lot to see him and she was no trouble at all but our last and shortest flight was the most challenging when she was 11 months old. Now we’ll be flying 14 hours and she’s a strong willed, very vocal little lady who rarely sleeps anywhere except her cot and I’m quietly dreading this trip but have to go. We have the option to fly direct on a not very good airline ( very cramped seating) or have a stopover on a better airline. Im happy to pay for a seat for her, she’s a big girl, but I doubt she would sleep in it...I would pay for a business class seat if she sat on my lap but I couldn’t afford a seat for her too. If anyone has any advice on which option has worked well for them I’d gratefully receive it.
