Hi - I have a short connection time - 2hr 30 min, flying Egypt Air, with Egypt Air ticket from LXR-CAI and then an Air Canada ticket for flight on Egypt Air - CAI-JFK. Both flights are Egypt Air but different ticket #s. Both flights use Terminal 3 at CAI.

1. As the tickets are different PNRs, is there any chance my bag can be checked through from LXR-CAI-JFK - i.e. I do not have to pick up the bag in Cairo?
2. Any recent experience. of CAI-JFK - is online check in possible?
3. Any Egypt Air transfer/ticket desk that I can use in Terminal 3 so I avoid getting into long lines for security/check-in? My bag is small and can be done as carry on instead of checked bag if I reduce weight etc.
4. Any other helpful ideas?

Thanks.
