Systems and methods for facilitating passengers to manage airline reservations within electronic messages are disclosed. Interactive content may be determined based on airline reservation information associated with the passengers. The interactive content may include content sets for the passengers to purchase flight options such as upgrading seats, meals, entertainment, and the like within the electronic message. The interactive content may include content sets for the passengers to interact with (e.g., select) offers by merchants. Targeted offers or advertisements may be obtained from the merchants by providing passenger information. In some examples, selection of targeted offers for presentation to the passenger in the electronic messages may be made based on historical information related to the passenger (e.g., such as product preferences manifested by the passengers in the past).
