I have flights
WAW-FRA-CMB-MLE. First leg is with LOT, the rest with Sri Lankan. The whole trip is under one e-ticket number.
Question: how does the check-in work for this - I can do FRA onwards check-in online on Sri Lankan website and then check-in for the WAW-FRA on LOT? Or we can do the check-in all the way already in WAW? Luggage I presume I can tag all the way from WAW to MLE?
Would be easier if both airlines in same alliance but this is not the case as I understand it.
