Well, reason I booked this early is because I am traveling with two kids so I want to get my seats confirmed. And Google Gemini tells me (well, many conflicting answers) earliest I can book is 180 days ahead, so I have it a try.
Yes we are traveling to Milano, but it’s to Milan airport. My wife is worried that a transit at Milan would be too chaotic with luggage’s and two kids running around, so we plan to get off at Domodossola then get a private transport to MXP airport directly.
