I understand your concern. I think 2hrs
is enough to transfer your luggages from one plane to another and more than enough for u to board ur plane to abu dabi.
Couple of yrs ago when i flew to ktm...my ny to london flight was delayed about 3hrs and my layover in london was also 3hrs so when i got off the plane in london i basically ran to my plane to barahain. I didnt miss the flight but my luggages were left behind.
So, i had to wait a day in ktm to get my luggages. You have to fill out a form and they will keep you luggages.
Planes dnt get delayed very often. I was traveling in december so mine was due to weather. If the deal is really good then i think u should buy the ticket.
Best of luck!
