Check with the airlines (websites should say) regarding Bassinets. It might depend more on the size of the actual aircraft than which airline. It's important to ring and book the bassinet seat as there are only two on each flight, but I am pretty sure you can do this after purchasing your ticket. It shouldn't really matter if it is a cheaper airline, as long as they have a bassinet and it is available. Car rental companies will rent you a baby seat for a small charge (like $10) but check it has been installed properly as installation is usually severely dodgy and needs adjustment. If you have a sling, probably easiest to carry DS in that at the airport as most airlines will not allow strollers on board, although some will allow you to take them to the gate and put them down the slide where they are lodged as cargo. If you are going to do that it is better to have a bag or cover for your stroller as it can be damaged by the slide. Again this depends on which aircraft and which gate it is leaving from, so given Archie is still little, I would put him in a sling and check your stroller. Strollers are sometimes considered oversize baggage which is annoying as you have to go to a separate desk to check them in/ pick them up, but they are usually included in your ticket if traveling with an infant. Again, as you're traveling alone, it will be easier to manage your luggage with DS in a sling. Don't be put off by all the above, I think your DS is pretty much the best age to travel with - he will probably sleep on the plane and still fits on the change table, and won't be charging up and down the aisles throughout the flight. If you can get the bassinet sorted you should be fine. Have a great trip!
