Getting back on the CC game after 2 years
1. You will pay anywhere from $100 to $1000+ depending on airline, airports touched and class of service for the infant. There are various threads in FT that you can research once you narrow down the alliance you wish to travel in.
2. You guys need to closed some Chase cards and reduce your total credit from Chase if you intend to apply for more chase cards.
3. Not many award ticket options to Nepal (KTM). If you cannot find seats think about flying to Delhi or another Indian airport with award availability and then buying a cheap round trip for cash (that you can use Citi Thank You or Barclays Arrival points to pay for)
