Masters

Hi,
Yes you can pursue PG from Canada as your backlogs are cleared so there is no issue in getting a student visa and studying abroad.
The decision on an application for a Canadian study permit will completely be based on one's individual application package. Usually good academic record ( especially marks of last major degree) , proper course selection (preferably showing progression in same field) consistent profile, sufficient proof of funding and a decent IELTS score and showing strong ties to your home country is seen as a standard benchmark to get the Canadian study permit. There may be more requirements, depending upon the citizenship of one's country.
Consistent profile and academic record is one of most important factors, Visa officers consider while issuing a study permit, since you have decent Marks in B.Tech. Most Canadian universities need at least B grade or minimum 60%-65% marks in final 2 years of a 4 years Bachelor's degree for students from India, Pakistan, Bangladesh, Nigeria etc. and an IELTS score of 6.5 overall (with no bands less than 6) (some top grade universities may require IELTS score of overall 7)/ equivalent score of TOEFL also accepted in most universities for being eligible to apply to Master degree programs.So you can get student visa as well as pursue PG from Canada without any issue.
All the best for your future.

Hi,
Actually it depends on which field you are interested upon. Both are related to travelling, so two of them have a good scope.
As you have done B.Tech, so you can surely opt for Masters. Both airport jobs as well as tourism has good career opportunity.
Being a very wide field, the scope of employment in tourism sector is very bright and the potential is still largely untapped. Career opportunities exist both in the public and private sector. In the public sector, there are opportunities in the Directorates and Departments of Tourism of the center and the state as Officers, information assistants, Tourist guides etc. Another good prospectus for qualified tourism professionals are in the private sector with travel agencies, tour operators, airlines, hotels, transport and cargo companies etc.
The opening up of the skies to private airlines and their emerging tie-ups with foreign airlines has removed bottlenecks in the transport and communication network resulting in easy flow of domestic and foreign tourists in the country. Since this is a new area of employment, not many qualified and experienced people are available and the promotion prospectus are also very bright and rapid. After a few years of experience, one can also start their own business by handling all travel requirements of a client and gradually building up business, taking on additional employees.
A degree in travel and tourism management equips you to work in such locations as a travel agency, a hotel, an airport, or any other hospitality-focused locale. Degree levels differ depending on the career, but all of these jobs require a certain subset of knowledge and the ability to multitask and communicate clearly with customers. Hence both have good scope for future. You can choose either of them based on your criteria of job and interest. I have given a brief overview of both above which you can refer and decide upon.
Hope it helps.
